| 摘 要： | 以花生壳为原料制备花生壳活性炭,进行了吸附去除水溶液中Cu2+和Ni2+的试验。研究了活性炭投加量、吸附时间、溶液pH、初始Cu2+和Ni2+质量浓度等因素对花生壳活性炭去除Cu2+、Ni2+作用的影响。结果表明,花生壳活性炭对重金属的吸附是一个快速反应过程,可在60 min内达到平衡。花生壳活性炭的投加量和溶液的pH对吸附效果有很大的影响,去除率随pH上升而增加,铜离子适宜的pH范围宽于镍离子。花生壳活性炭是一种廉价、有效的吸附剂,对溶液中铜离子的去除效果好于镍离子。

| Abstract: | The preparation of activated carbon from peanut shell and its adsorption to Cu2+ and Ni2+ are studied.The adsorption of peanut shell active carbon to heavy metals was a rapid reaction with only {60 min} for equilibrium.The adsorption of peanut shell active carbon to heavy metals is dosage dependent.The adsorption of the heavy metal increased with increasing pH.The removal rate of Cu2+ by peanut shell active carbon is higher than that of Ni2+. |
