摘　　要： 以景泰风化煤作吸附剂,常温下对水溶液中的Cu2+进行了吸附实验研究,探讨了吸附平衡和吸附机理,通过正交实验考察了影响吸附率的因素.结果表明,风化煤对Cu2+有较强的吸附性能,吸附平衡基本符合Langmuir模型,最大吸附量可达24.39mg/g,pH是影响吸附效果的最主要因素. The adsorption of Cu^2＋ in aqueous solution with Jingtai weathered coal at normal temperature, the adsorption equilibrium and the mechanism of adsorption were studied. The influencing factors in the adsorption of Cu^2＋ were discussed by cross-over experiment. The results show that the weathered coal has good adsorption capacity, the adsorption isotherms mainly conformed to Langmuir equation, the maximum adsorption quantity could attain 24.39 mg/g and pH is the strongest factor influencing the disposal.
