摘要:
Cr(VI)是一种公认的致癌物质,用途广泛且造成水体突发性污染的可能性大.本文比较分析了活性
炭和活性氧化铝对六价铬的吸附性能,并对两种吸附剂用于水体六价铬污染处理的可行性进行了讨论.结果
表明,初始pH值、投加量、吸附时间对六价铬的吸附效果影响较大,分别在pH 为2和3的酸性条件下效果
最好,活性炭与活性氧化铝对铬的吸附去除率分别可达96.06%和84.18%.吸附效果在一定范围内随着投加
量的增大、吸附时间的延长而提高,而后达到平衡.两者对六价铬的吸附等温线与Langmuir方程和Freundlich
方程都较符合,且活性炭效果更好.
Abstract:
Cr(VI)is considered to be potentially carcinogenic to mankind,and has the potential pollution to water.Activated
 alumina and activated carbon were used as adsorbents of Cr(VI)from aqueous solutions and the effect of operating
parameters were investigated.The results show that pH value,adsorbent concentration and contact time were important
effect parameters.The maximum removal rate of Cr(VI)was found at pH 2for activated carbon and at pH 3for activated
alumina,96.06%and 84.18%,respectively.Adsorption performance increased with dosage and adsorption time increased
and then remained constant when reaching to equilibrium.Langmuir
