改性上林沸石吸附选矿废水的研究

Study on Modifing Shanglin Zeolite Adsorption of Beneficiation Wastewater

分别采用盐酸和氢氧化钠浸渍方法对上林沸石改性,改性沸石在溶液中搅拌情况下,吸附选矿废水中金属离子。考察溶液pH值、沸石粒度、吸附时间对Cu^(2+)和Zn^(2+)离子吸附性能的影响,溶液中金属离子浓度通过原子吸收光谱分析,结果表明,选矿废水中锌、铜离子去除率达99.8%。

Impregnation method of the hydrochloric acid or sodium hydroxide were used to modify the zeolite in shanglin town,and the zeolite was adsorbed in the solution of metal ions in the mineral processing wastewater. The effects of p H value of solution,zeolite particle size and adsorption time on the adsorption properties of Cu^2＋ and Zn^2＋ in mineral processing wastewater were investigated.The concentration of metal ions in the solution was analyzed by atomic absorption spectrometry. The results showed that the removal rate of zinc and copper ions in the beneficiation wastewater was 99. 8%.
