摘　　要：利用磷酸处理微波照射制备花生壳活性炭,以一定浓度的结晶紫溶液为模拟染料废水,研究了吸附剂粒径、溶液pH值、结晶紫的初始浓度、吸附剂用量、吸附时间、吸附温度对结晶紫吸附性能的影响。结果表明花生壳活性炭是具有高去除率的廉价吸附剂,最大去除率达96%。结晶紫染料在花生壳活性炭上的吸附过程符合二级动力学模型和Freundlich等温吸附方程。The peanut shell active carbon is prepared with phosphoric acid treatment and microwave irradiation and then is used as an adsorbent to adsorb crystal violet from aqueous solution,which served as simulated dye waste water,to study the influences of some factors,including the particle size of the peanut shell active carbon,pH,initial concentration of crystal violet,dosage of the peanut shell active carbon,adsorption time and adsorption temperature,on adsorptive property to crystal violet.The results show that the peanut shell active carbon is a kind effective and low cost adsorbent.The best removal rate of crystal violet is about 96%.The adsorption process of the peanut shell active carbon with crystal violet follows the pseudo-second order kinetics model and Freundlich adsorption isotherm.
