摘要
采用静态吸附实验考察了不同条件下废弃蛋壳吸附剂对总铁浓度为2.866mg/L的微污染饮用水处理效果的影响。实验结果表明,静态吸附总铁浓度为2.866mg/L的100mL微污染饮用水,当吸附剂用量为3.0g,介质pH值为5.0,吸附时间为2.0h时,铁的去除率可以达到98.81%。总铁浓度下降为0.034mg/L,达到了GB5749-85的标准。文章同时对吸附等温线等进行了实验说明。
Effects on treatment of micro-polluted water with concentration of Fe 2.866mg/L were studied by means of static absorption under different conditions.Experimental results showed that under adsorbent dosage 3.0g,optimum pH 5.0 and adsorption time about 120min in 100mL micro-polluted water,the adsorption rate of Fe was up to 98.81%,and concentration of Fe can be reduced to 0.034mg/L,which comes up to the standard of GB5749-85.In the meantime,the adsorption isotherm,Langmuir adsorption isotherm and Freundlich ...
