This book was released on 2024-05-06 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characteristics of the activated carbon and the changes in that of the modified activated carbon were verified by SEM, EDX, XRD, XPS, BET and FT-IR analyses;·The SEM studies indicate the formation of regular structure with net thin fibrils of AC; and spherical shape and smaller than 18nm in size of porous surface created in AC-MnO2-NC. The EDX studies show the presence of the elements, Carbon, Oxygen, Sodium, Magnesium, Phosphorous, Sulphur, Chlorine, Potassium and Calcium in AC. In case of AC-MnO2-NC in addition to these elements, the capping Manganese is proved. The XRD studies indicate the formation of short range crystalline structure and abundance of amorphous structure of the activated carbon and the modified activated carbon. The presence of Carbon and Oxygen in the activated carbon and in addition to these elements, the presence of Manganese in the modified activated carbon are also revealed by XPS studies. The BET studies show that the surface area of AC is 83.54m2/g and that for AC-MnO2-NC is 147.76m2/g. The FT-IR study suggest that the capping of MnO2 in modified activated carbon and the presence of the functional groups viz., -OH, -C=O, -C=C, -C-H, -CH2, -CH3 in the two adsorbents. The percentage of dye removal increases with increasing agitation time and adsorbent dose and decreases with increasing initial dye concentration. An increase in the time of agitation was found to be directly proportional to the amount of dye adsorbed per unit weight of the adsorbent. The adsorption of dyes from aqueous solutions attain equilibrium at different agitation time which depend on initial dye concentrations and initial pH of the dye solutions.

This book was released on 2012 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Batik industry is a very famous textile industry in Malaysia especially in East Coast of Peninsular Malaysia. Started in small scale, today it has become one of the highest economic growths in Malaysia due to high demands locally and from abroad. However, the wastewater from textile industry contributes to water pollution since it utilizes a lot of chemicals. Preliminary studies show that the wastewater from this homemade textile industry contains grease, wax, heavy metal, surfactant, suspended solid, and dyes (organic and inorganic). This research was done to study the potential of granular activated carbon (GAC) for the adsorption of synthetic batik dye (SBD) from aqueous solution by the variation of solution with different contact time, adsorbent dosage and initial concentration of SBD. Activated carbon (AC) is commonly known as one of the great adsorbents in adsorption process. For this study, granular activated carbon (GAC) has been used since it is preferred for all adsorption of gases and vapors as their rate of diffusion are faster. The synthetic batik dye has been chose because the research about this topic has not been done yet. There are three parameters that will be investigated; effect of adsorbent dosage (w), effect of contact time and effect of initial synthetic batik dye concentration. All results from the experiment were being analyzed using UV-Visible Spectrophotometer (UV-Vis). The results show that the color of the dye changes with different contact time, adsorbent dosage and also different initial concentration of synthetic batik dye. The data collected could be used to improve the effectiveness of dye removal from the batik industry wastewater using granular activated carbon (GAC). The research showed the applicability of GAC to adsorb the color of SBD. For SBD initial concentration shows the highest percentage concentration difference which is 69.75 % occurring at 0.2 g/L. While for adsorbent dosage, the highest dosage which is 60 gram get the highest percentage; 94.77 %. And for contact time, the longest contact time which is 20 minutes gets the highest percentage where the percentage is 95.06 %.

Available in PDF, EPUB and Kindle. Book excerpt: Water of high quality is essential to human life and water of acceptable quality is essential for agriculture, industrial, domestic and commercial uses. The discharge of dye wastewaters into natural streams and rivers from the textile industry poses severe problems. Restoring water quality to its original states could be expensive. Adsorption has been found to be superior to other treatment methods for water re-use in terms of flexibility of design and ease of operation. On the environment and economic side, the selection of the best adsorbent is a key issue that receives large attention. This book provides an interesting contribution to the water treatment process by adding current less explored knowledge of adsorption. The technical feasibility of various adsorbents for dyes removal from contaminated water has been reviewed. Instead of using commercial activated carbon, the author of this book has worked on industrial waste material. In this book, locally available mangrove bark was studied for its potential use as an adsorbent for the removal of different types of dyes from aqueous solution. Factor affecting the efficiency of dyes removal were evaluated.

This book was released on 2016 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Textile dyes are one of the wastewater contaminants. Treatment of industrial wastewater considers a challenge when choosing effective approaches. Adsorption on activated carbon is one of the superior techniques were evaluated in previous studies and considered in this thesis. In practice, the adsorption capacity of the active sits on the carbon was high. Consequently, activated carbon was used to remove textile dyes (Dylon Yellow) from wastewater under different parameters that may affect the adsorption of reactive dye. In principle, the influence of various factors such as dye type, carbon type, contacting time between carbon and dye solutions, pH, and salinity was investigated. Minitab software was used to design the experiment and evaluated to determine the significance of each factor. As a result, this work has showed that pH and salinity has no impact on the adsorption process. However, this study confirmed the previous results of influencing of dye type, carbon type and contacting time between dye solutions and carbon on the adsorption of reactive dye on activated carbon. Increasing the contacting time between carbon and dye solution allows the carbon to absorb larger amount of dye. Further, variation of carbon type or dye type plays an important role in influencing the ability of carbon to absorb dye. --

Book excerpt: The research is dedicated to studies of activated carbons performance in the wastewater process of dye removal. The experiment was performed to assess the efficiency of the commercial activated carbons (Fl00, F600, F820, SGL 8x30, CAL, AP4-60, OLC12x30) in adsorption process for Dylon Blue Dye. The effect of type of activated carbon, dye, salinity, pH and contact time, were studied. Minitab software was used to design an experiment to collectively evaluate these factors. The experiments were performed by measuring the absorbances of the solutions before and after contact with the activated carbon. The absorbance was evaluated with UV-Vis spectrophotometer. The adsorption of the dye took place on all the studied activated carbon samples, thus the dye concentration reduced comparing to the initial solutions. Results of the study indicated that pH and salinity did not have any significant effect of the adsorption of the dye on the carbon. However, type of carbon and contact time were shown to influence adsorption significantly. Lack of effect of pH and salinity in current study contrasts finding reported in other studies --
