摘　　要：为了探索鸡蛋壳对实验室废水中六价铬的去除性能,分别考察了鸡蛋壳用量、振荡时间、溶液体系温度及pH对鸡蛋壳吸附六价铬性能的影响,结果表明,鸡蛋壳用量为2.0 g,pH为2.05,振荡时间为35 min,体系温度为25℃时,鸡蛋壳对六价铬的吸附效果最高,可达95%左右,不比活性炭吸附去除效果差。In order to study the removal of Cr(Ⅳ)from laboratory wastewater by solid waste eggshell,the effects of eggshell dosage,oscillation time,solution temperature and pH on the adsorption of Cr(Ⅳ)on eggshell were investigated.The results showed that when the dosage of eggshell was 2.0 g,pH was 2.05,the oscillating time was about 35 min,and the temperature of the system was about 25℃,the highest adsorption rate of Cr(Ⅳ)was about 95%,which was not lower than that of activated carbon.
