摘要
研究了低温竹炭的粒径、用量、Cr(VI)初始浓度与吸附时间对Cr(VI)离子吸附性能的影响,采用正交试验法对最佳吸附条件进行优化。结果表明,低温竹炭对Cr(VI)离子的吸附最佳条件是:竹炭粒度80～100目,吸附时间120 min,Cr溶液初始浓度10 mg/L,竹炭用量0.9 mg。
The adsorption properties of low temperature bamboo-charcoal for Cr（Ⅵ） ion in water solution were studied.Effects of some factors,such as particle size and quantity of bamboo charcoal,initial concentration of the solution,absorbing time,on the removing of Cr（Ⅵ） ion from water solution were investigated.The optimal absorbing condition for Cr（Ⅵ） by orthogonal test showed as follows： bamboo charcoal particle size at 80-100 mesh,absorbing time 120 minutes,initial concentration of Cr（Ⅵ） ion 10 mg/L,quantity of bamboo charcoal 0.9 mg.
