摘　　要：以景泰风化煤作吸附剂,对常温下水溶液中的Ni(Ⅱ)进行了吸附实验研究,探讨了吸附平衡、影响吸附的因素和吸附机理。结果表明,风化煤对Ni(Ⅱ)的吸附表现出Langmuir特征,在pH值6.0左右吸附效果较好,最大吸附量可达16.47mg/g。The adsorption of Ni(Ⅱ) in aqueous solution with Jingtai weathered coal at normal temperature, the adsorption equilibrium, the effect elements and the mechanism of adsorption were studied. The results indicate that the adsorption of the weathered coal for Ni(Ⅱ) mainly conformed to Langmuir equation, the adsorption property is better when pH is about 6.0 and the maximum adsorption quantity could reach 16.47 mg/g.
