摘要
研究了改性花生壳对Cr6+的吸附作用,并探讨了溶液的pH值、Cr6+初始浓度、吸附时间、温度及改性花生壳用量等因素对Cr6+吸附效果的影响。结果表明,在温度为33℃、改性花生壳用量为1.0 g、20 mg.L-1的Cr6+溶液50mL、溶液的pH值为2.0、振荡吸附时间为120 min的条件下,Cr6+的吸附去除率达到了98.4%。
Adsorption of Cr^6+ by modified peanut shell was studied. The effects of pH value, initial concentration of Cr^6+,contact time, temperature and modified peanut shell dosage on adsorption had been investigated. The results indicated that modified peanut shell had good adsorption to Cr^6+. In condition of 33℃, 1.0 g modified peanut shell,50 mE 20 mg·L^-1 Cr^6+ solution, the initial pH value 2.0 and contact time 120 min,the adsorption rate of Cr^6+ could be up to 98.4%.
