橘皮对污水中重金属离子的吸附作用
|
摘要
利用农林废弃物橘子皮对含有Ni、Pb、Zn的重金属废水进行处理。通过模拟柱层析分离方法研究溶液pH值、吸附剂粒径、污水浓度、吸附剂用量等因素对吸附效果的影响。通过正交试验获得最佳的吸附条件。在最佳吸附条件下处理了生活污水、工业污水、矿山污水。结果表明,吸附剂粒径为380μm,吸附剂用量为15 g/L,pH为4时,污水初始浓度为20 mg/L,对Pb、Ni、Zn的最大吸附率分别为87. 6%、75. 2%和81. 4%。
The absorption of orange peel to heavy metal ion of Ni,Pb and Zn in sewage was studied. The influence of pH value,adsorbent particle size,sewage concentration and adsorbent amount on the adsorption effect was studied by simulated column chromatography. The optimum adsorption conditions were obtained by orthogonal?experiment,under which the water in the domestic sewage,industrial effluents and mine sewage were treated. The results showed that the maximum adsorption rate of Pb,Ni and Zn was 87. 6%,75. 2% and 81. 4%,respectively,when the adsorbent size was 380 μm,the adsorbent dosage was 15 g/L and pH value was 4 and the initial sewage concentration was 20 mg/L.
