| 摘 要： | 通过静态吸附试验，研究了粉煤灰滤料对水中Ni^2＋的吸附作用，探讨了吸附剂投加量、吸附时间、溶液pH值以及初始浓度对Ni^2＋吸附效果的影响，拟合了吸附等温线。结果表明，当粉煤灰滤料投加量为30g／L，溶液初始浓度为10mg／L，pH=7时，在30℃、180r／min的转速条件下振荡90min，Ni^2＋的去除率可达到95．2％。经过拟合，粉煤灰滤料对水中Ni^2＋的吸附符合Freundlich和Langmuir吸附等温模型。

| Abstract: | Adsorption behavior of Ni^2＋ on fly ash filter material was studied by static adsorption experiment. The influence of absorbent dosage, adsorption time, pH and initial concentration on adsorption were inv model was drafted. The results showed that removal ratio of Ni^2＋ with initial concentration of estigated. Adsorption isotherm 10mg/L attained 95.2% on the operation condition of 30g/L dosage, solution pH 7, temperature of 30℃ and stirring speed of 180r/min for 90 min. After mathe- matical simulation, adsorption of Ni^2＋ on fly ash filter material complied to Freundlich and Langmuir adsorption isotherm model. |
