Title
Efficiency of Reactive Black 5 dye removals and determination of Isotherm Models in aqueous solution by use of activated carbon made of walnut wood
English Abstract
Industrial textile colors and other industrial dying materials are one of the important organic materials that increase environmental impacts. There-fore, it is necessary to treat those effluents prior to discharge into environment. Various parameters including initial concentration of dye, effect of mass of adsorbent on color removal and pH were surveyed. For determina-tion of residual concentration of dye, a spectrometry set UV/VISLambda 25.UV/VIS(Perkin Elmer)at 599 wavelengths was used. Various parameters including initial concentration of dye, effect of mass of adsorbent on color removal and pH were surveyed. Results indicated that removal of Rea-ctive Black5 dye depend on Langmuir (R2>0.96), respectively. In the study kf was 1.47 and amount of adsorbed reactive black5 was qm(mg/g)=14.08 for mass unit of activated carbon. In general, the results of study showed that activated carbon made of walnut wood can be used as an effective adsorbent for the removal of Azo dyes.
