| 摘 要： | 以景泰风化煤作吸附剂，常温下对水溶液中的Cu^2＋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Cu^2＋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．

| Abstract: | 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. |
