摘要
研究了一定量的粉煤灰基质滤料对溶液中可溶性Cu2+的静态吸附性能,考察了初始浓度、温度、溶液体积对粉煤灰基质滤料的吸附性能的影响,分析了不同条件下粉煤灰基质滤料的吸附过程。结果表明,最佳吸附温度约为85℃时,去除率达到91.43%。另外,随着Cu2+初始浓度的增大,滤料对Cu2+的吸附量增加,但吸附去除率下降;而当Cu2+的溶液体积增大时,滤料对Cu2+的单位吸附量减少,去除率降低。
The adsorption characteristic of copper ion on fly ash filter material was studied.The effect of initial concentration,temperature,initial solution volume on the cupreous adsorption was investigated.The results showed the removal ratio was 91.43% with the optimal temperature of 85 ℃.With the increasing of initial concentration,the adsorption capacity of copper ion increased while the removal ratio declined.And with the rise of initial volume,the adsorption capacity and removal ratio decreased.
