Carbon prepared from silk cotton hull was used to remove a textile dye (reactive blue MR) from aqueous solution by an adsorption technique under varying conditions of agitation time, dye concentration, adsorbent dose and pH. Adsorption depended on solution pH, dye concentration, carbon concentration and contact time. Equilibrium was attained with in 60 min. Adsorption followed both Langmuir and Freundlich isotherm models. The adsorption capacity was found to be 12.9 mg/g at an initial pH of 2+/-0.2 for the particle size of 125-250 microm at room temperature (30+/-2 degrees C).
由木棉壳制备的碳通过吸附技术在不同的搅拌时间、染料浓度、吸附剂剂量和pH条件下从水溶液中去除一种纺织染料（活性蓝MR）。吸附取决于溶液pH、染料浓度、碳浓度和接触时间。60分钟内达到平衡。吸附符合朗缪尔和弗伦德利希等温线模型。在室温（30±2℃）下，对于粒径为125 - 250微米的样品，初始pH为2±0.2时，吸附容量为12.9毫克/克。
