摘要: Adsorbent materials have been produced from sewage sludge and discarded tyres. Their physical structures chemical surfaces differ according to their origin production process. However, all the activated carbons show a good development of mesopore structure. The adsorption equilibriums methylene blue sandolan brilliant red N-BG 125 (an industrial dye) onto generated analysed described in terms Freundlich isotherm. best results were those corresponding adsorbent obtained chemically with ZnCl2. effect temperature on dyes was addressed thermodynamic parameters (ΔH, ΔS ΔG) determined for each studied systems. It found that process endothermic spontaneous cases.
