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.

Book excerpt: In this study, removal of water-soluble dyes from aqueous solution by peanut hull as adsorbent was investigated. Breeding of peanut hull were KAC431 and KAC1. Water-soluble dyes in this study are direct yellow, direct red. Reactive blue and reactive yellow dyes. The suspendion was stirred for 25 hours at 30 degrees celsius and 1 atm. Parameters such as initial concentration of dye solution of 10, 30, and 50 milligram per liter, pH of initial dye solution of 5, 7, and 9, and particle size of adsorbent of 0.150-0.180, 0.180-0.210, and 0.210-0.300 millimeter are studied. The results show that peanut hull as adsorbent can be used to remove dye from aqueous solution. Direct yellow dye can be effectively adsorbed on both breeding of peanut hull when the initial concentration of dye solution is 50 milligram per liter, particle size of adsorbent is in the range of 0.150-0.180 millimeter, and initial pH of dye solution is 5. Adsorption ability of each type of dyes slightly decreases with increasing initial concentration of dye solutions. Adsorption ability of dye depends on components of dye i'n dye solution.

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.

Download or read book Treatment of Textile Dyes Wastewater by Coconut Coir Activated Carbon written by Taimur Khan and published by LAP Lambert Academic Publishing. This book was released on 2014-05-21 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Textile dyes have adverse effects on human beings and aquatic life. Textile dye waste is a potential source of surface and ground water contamination if it is not properly collected, treated and disposed of. The main objective of the research was to prepare activated carbon from an agricultural solid waste, coconut coir and to determine its effectiveness in removing textile dyes from aqueous solution and in textile dye waste treatment. The coconut coir activated carbon (CCAC) and a commercial activated carbon (CAC) were characterised in terms of ash content, bulk density, pH, pHZPC, surface area, micropore area, micropore volume, average pore diameter, surface morphology, surface acidic functional groups, basic sites and surface functional groups. Adsorption of four different classes of textile dyes, namely Acid Red 18 (AR 18), Disperse Red 343 (DR 343), Reactive Yellow 15 (RY 15) and Direct Blue 86 (DB 86) by CCAC and CAC were examined.
