This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sorption of two reactive dyes, namely Remazol Brilliant Blue and Orange G Pure, on activated carbon, has been studied. Three effects on adsorption of dye by activated carbon had been studies. Three effect on adsorption of dye by activated carbon had been studies which are flow rate of dye when entered the column (5,10,15 mn/min) when bed heightand initial concentration are contant ( 15 cm and 200 mg/l), initial concentration of dye ( 100,200, 300 mg/l) with bed height (15cm) and flow rate ( 5 ml/min) and bed height (10,15,20 cm) with constant flow rate (5 ml/min) and initial concentration (200mg/l) .The removal of dye was faster in initial stages, gradually decreasing pattern and became contant after equilibrium was achieved. The initial dye concentration of the effluent is important since a given mass of adsorbent can only adsorb a fixed point amount of dye.

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.
Download or read book Adsorption of Basic and Acid Dyes Using Palm Kernel Shell based Activated Carbon written by Jumasiah Arsyad and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of batch laboratory studies were conducted in order to investigate the practicability of palm kernel shell (PKS)-based activated carbon for removal of basic dye, Basic Blue 9 (BB 9) and acid dye, Acid Orange 52 (AO 52) from their aqueous solutions. Three different particle sizes of PKS were used and categorized as PKS - S, PKS - M and PKS - L. The adsorption capacities of the PKS-based activated carbons were compared with those of commercial grade coal-based activated carbons at the same conditions. All batch experiments were carried out at a constant temperature of 28oC (±2oC) using incubator shaker that operated at 150 rpm. Batch equilibrium study shows that Adsorption of BB 9 and AO 52 were highly pH dependent. Removal of BB 9 increased with pH with maximum removal observed at pH 7.0, and decreased thereafter with further increase in the initial pH. However, pH effect on AO 52 removal shows that AO 52 removal decreased with an increase in initial pH with the optimum initial was observed at 3.5. batch equilibrium data also a had good agreement with the Langmuir, Freundlich and Redlich-Peterson isotherm models with correlation coefficients > 0.9. Overall, the Redlich-Peterson isotherm showed the best fit for all adsorbents under investigation in terms of correlation coefficient as well as error analysis of the results. For all the systems in this study, the analysis of isotherm shape factor showed that adsorption was favorable. For the adsorbents under investigation, PKS-S has the highest adsorption capacity followed by PKS-M. PKS-L and commercial coal based pellet form have almost equally-balanced adsorption capacity. Of all the adsorbents, commercial coal-based in powder form exhibits the lowest adsorption capacity. Obtained results revealed that PKS based activated carbon is a highly potential alternative adsorbent for treatment of dye-containing wastewater. The maximum capacity of the adsorbents for BB 9 were 333.33 mg/g, 322.58 mg/g and 212.77 mg/g for PKS - S, PKS - M and PKS - L, respectively, while for powder and pellet commercial grade coal based, the capacities were 204.08 mg/g and 217.39 mg/g, respectively. On the other hand, the maximum capacities of the same adsorbents for AO 52 were 344.83 mg/g, 333.33 mg/g, 263.16 mg/g, 238.09 mg/g and 322.58 mg/g, respectively. Adsorption capacities of the same adsorbents were found to be higher for adsorption of AO 52 compared to those of BB 9 due to the smaller molecular size of the former. Batch kinetic studies were also performed to investigate the rate limiting of the adsorption process. Results obtained revealed that the adsorption of both BB 9 and AO 52 was rapid at the beginning, but approached equilibrium slowly. Experimental data can be modeled using pseudo-second-order kinetic model as first order kinetic model does not represent the whole range of adsorption process. Other than that, intraparticle diffusion was found to be prominent at a certain stage of adsorption but it would not be the only limiting step that controlled the adsorption dynamic. Kinetic data also showed that the adsorption rates were a function of initial adsorbate concentration, adsorbent particle size and adsorbent mass. For all systems under consideration, the values of k2 increased significantly as adsorbent dose increases. Nevertheless, the values of k2 were inversely proportional to the initial adsorbate concentration and adsorbent particle size. On the other hand, values of kp were found to be directly proportional to the initial adsorbate concentration but decreased gradually as adsorbent particle size and adsorbent dose increases.

Book excerpt: In this project the absorption of textile dye on commercial activated carbon is studied. The interaction between adsorbed molecules and the carbon surface were studied at different dye concentrations. The concentrations of dyes in the solution after adsorption process were determined using UV-Vis spectroscopy and the Beer-Lambert law. The Langmuir isotherm theoretical model was used in order to obtain characteristic parameters of adsorbent and adsorbate. In addition, the effects of the different dyes between the carbon surface and water hardness. pH and salinity on the absorption process were studied. In the study of (Red pro032) dye there are some of factors effected such as carbon and salinity. The absorption is affected by the type of carbon and salinity. Water hardness and pH effected in the absorption rate. The purpose of this experimental work, to determine which of these factors are most significant with the goal of establishing a model to predict dye absorbance in wastewater. --

Book excerpt: Present study deals with the adsorption of textile dye from aqueous solution on commercial activated carbon. The adsorption of Procion 072 Medium Blue dye on carbon was assessed by measuring absorbance using a UV-Vis spectrophotometer. The main goal of this research was to understand the nature of the interaction between adsorbed molecules of the dye by activated carbon under various conditions of pH, Salinity, time and types of Carbon. Results of this research showed good correlation with the Langmuir isotherm model. Factors that could affect the adsorption were assessed. Significant influence on adsorption was found in contact time, type of carbon and type of dyes. Salinity of water and pH on other hand showed negligible influence on adsorption of the dye. Minitab 16® Software was applied to design the experiments and to identify the significance of each factor. Furthermore, it was generated the randomized run orders for the experiments. A factorial experiments has five factors, three factors Carbon type, Dye type and pH with 3 levels, and two factors time and salinity with 2 levels, also it has 216 experimental conditions.
