This book was released on 2006 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semiconductor industry currently requires large volumes of ultra pure water (UPW), a point of concern due to the potential effects on the environment. Although reduction of water consumption by the industry is challenging, it can be accomplished by implementation of different strategies such as the reuse and recycling of water, the development of more efficient wet cleans and wet processes, and the conversion to dry process. The lack of a systematic approach to determine the optimum combination of water recycling and reusing and the optimum type of process configuration for recycle treatment need to be addressed in order to achieve more efficient water conservation. Specifically, multi-component interactions in ion exchange processes and the effect of these interactions on the separation efficiency have been neglected when dealing with water reusing and recycling. Ion exchange resins initially containing different concentrations of impurities were utilized in experiments to determine the effect that organic and ionic contaminants initially contained in the ion exchange resin have on the adsorption of ionic compounds. Experiments were performed with the tested ion exchange resins to determine the effect of organic compounds in the liquid phase. A combination of experimental and modeling methods were utilized to determine the fundamental equilibrium and kinetic parameters for ion-ion and/or ion-organic interactions. The concentrations under investigation are relevant to the ion exchange application in industrial ultra-pure water plants with. Experiments showed that adsorption of ionic compounds were affected by the amount of organic and ionic contaminants initially contained in the ion exchange resin. Additionally, experiments showed that the adsorption of organic compounds affects the capacity of the ion exchange resin, thus changing the efficiency of the system. The effect of organic impurities is not only due to the degradation of the exchange media, but also due to specific chemical interactions. These chemical interactions may enhance the adsorption kinetics; however, even in the case of kinetic enhancement, the key inhibition effect appears to be due to ionic transport effects, which cause pore and/or site blockage. By incorporating an organic removal process, such as granular activated carbon (GAC) or UV-oxidation to the recycle purification sequence, greater efficiency of the overall separation system can be achieved, resulting in reduced water usage and waste generation.

Download or read book Ion Exchange Advances written by M.J. Slater and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at the Sixth International Ion Exchange Conference organised by the SCI and held at Churchill College, Cambridge, UK, in July 1992. As on previous occasions, most recently in 1988, the organising committee did not engage plenary speakers but decided to solicit state-of-the-art contributions from the ion exchange community. This book contains the refereed papers presented at the meeting, whether in poster or oral form. Extra papers were presented at the meeting as posters because they were not available in time for refereeing purposes. The subject matter of the meeting and therefore the contents of the book is subdivided into seven separate topic areas as follows: resin developments; water treatment; fundamentals; biotechnology, food and pharmaceuticals; environmental and pollution control; membranes, inorganic materials and nuclear; and hydrometallurgy. The coverage of the meeting is similar to 1988 although there are fewer subdivisions on this occasion. The more restricted coverage this time reflects the smaller number of papers offered by authors. This is probably due to the world wide industrial recession which has affected commercial development and exploitation of the technology and restricts the ability of practitioners and academics to contribute to and attend international meetings. Nevertheless, the advances in biotechnology, growing concern about the environment and the. need for novel separation processes have provided sufficient impetus to stimulate a sufficient number of workers in the field.

Download or read book Protein Transport and Adsorption in Polymer modified Ion exchange Media written by Brian D. Bowes and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion-exchange chromatography can be a powerful tool for protein purification. New composite ion-exchange resins that combine rigid base matrices with softer polymer layers that have high adsorption capacity and enhanced uptake potential are emerging as attractive options for high-productivity purification processes. However, as the mechanistic origins of the improvements observed for these polymer-modified resins are not fully understood, examination of the effects of the polymer modifiers is warranted. Thus, significant efforts were undertaken to characterize the similarities and differences between a variety of resins with and without polymer modifiers. The characterization included measurements of equilibrium protein adsorption capacities, protein uptake rates, and column breakthrough behavior. In this work, the primary resins used were the traditional agarose-based resin SP Sepharose FF and the dextran-modified agarose resins SP Sepharose XL and Capto S. SP Sepharose FF and SP Sepharose XL made a particularly useful pair of resins to compare because the underlying agarose base matrix is the same for both. Thus, it was anticipated that it would be possible to examine some of the direct consequences of the dextran modification. The role of protein size was also an important consideration here. The small protein lysozyme, the moderate protein lactoferrin, and a large monoclonal antibody were used to test size effects. Experimental techniques were also chosen to study behavior at varied length scales, ranging from the column scale down to the individual-particle scale. Protein adsorption isotherms were measured on a traditional agarose-based resin and on two dextran-modified agarose-based resins. Higher equilibrium capacities were achievable for the dextran-modified resin and seemed to be attributable to volumetric partitioning of protein into the dextran layer compared to the monolayer adsorption on the agarose surface for the traditional resin. For a small protein, isocratic retention experiments revealed that the retention mechanism was quite similar between the two resin classes, suggesting that the dextran does not significantly change the nature of the protein-resin interaction. However, larger proteins were increasingly excluded from the dextran layer as salt concentrations were increased, leading to suppressed equilibrium adsorption capacity at intermediate salt levels. Knowledge of the protein and resin properties were used to rationalize the maximum equilibrium capacities that might be expected on the dextran-modified resins and revealed that the capacities are typically limited by the available volume for adsorption, but that the capacity might be limited by the available resin charge when the protein charge density is high relative to that on the resin. Column breakthrough experiments revealed high achievable dynamic binding capacities for the dextran-modified resins. For both resin classes, dynamic capacities were typically controlled by intraparticle transport limitations at low salt levels, especially for the larger proteins, and were generally limited by equilibrium capacities at higher salt levels. However, the transition between the intraparticle uptake control and the equilibrium capacity control occurred at different salt levels between the resin classes, suggesting a fundamental difference in the balance of adsorption and transport in the resins. Likewise, confocal microscopy experiments showed that, in spite of the similar protein retention properties, uptake was significantly enhanced on the dextran-modified resins, again reflecting a difference in the interplay between protein adsorption and transport. Equilibrium capacity and intraparticle diffusivity information were used to compare predictions from limiting models with experimental breakthrough data. While the agreement was good for the traditional resin, significant discrepancies were observed for the dextran-modified resins. The primary feature hypothesized to be lacking from the limiting models was a slow approach to equilibrium caused by an initially inefficient packing of protein within the dextran layer that gradually improves over time. A conceptual model accounting for this behavior was developed and showed some success in capturing the correct experimental behavior. Additionally, custom variants were used to examine the effects of the resin dextran content and charge density on protein transport and adsorption. Isocratic retention experiments revealed that increasing the dextran content could increase the severity of the high-salt exclusion of protein from the dextran, but that increasing the charge density provides an increased electrostatic driving force that can help overcome this steric exclusion. For the most part, the effect of dextran content was difficult to isolate, but the charge density was shown to correlate well with trends in adsorption capacity, isocratic retention times, and uptake and desorption rates. It was speculated from a number of observations that resins with an intermediate charge density should give rise to the highest achievable dynamic binding capacities and experimental investigations seemed to confirm this hypothesis. Finally, observations were made on a traditional methacrylate-based resin and on a resin with the same base matrix, but modified with proprietary polymers. Some effects of polymer modification similar to those for the agarose-based resins were observed, but some differences were attributable to differences in the resin structures. For example, the greater enhancement in equilibrium capacity with polymer-modification of the methacrylate-based resin could be attributed to the smaller specific surface area of the underlying methacrylate base matrix compared to that of the agarose materials. Additionally, adsorption and transport information seemed to indicate that the polymer-modifiers in the methacrylate-based resin are more subject to swelling and shrinking with changes in salt concentration than are the dextran-modifiers in the agarose media. Thus, while knowledge of the identity of the proprietary polymer could certainly enhance understanding of resin performance, some functional properties and consequences of the polymer were still evident.
