| 摘 要： | 研究了竹炭的粒径与用量、罗丹明B溶液的pH值与初始浓度、吸附时间和温度等因素对去除率的影响.研究结果表明:竹炭对罗丹明B吸附随其用量的增加而增大;罗丹明B初始浓度增大,竹炭对其去除率减小;溶液的pH值为3.0～5.0时,吸附效果好;竹炭对罗丹明B的吸附可在3h达到平衡.最佳吸附温度为70℃,等温吸附服从Freundlich方程式.竹炭是较为理想的吸附罗丹明B的材料.

| Abstract: | The adsorption properties of bamboo-charcoal for Rhodamine B in water solution were studied.Effects of factors such as quantity of bamboo charcoal,pH and initial concentration of the solution,absorbing time and temperature on the removing of Rhodamine B from water solution were investigated.The results show that adsorption capacity of bamboo-charcoal particles increases with the increase of their quantity.However,with the increase of initial concentration of Rhodamine B,adsorption ratio reduces.When pH valu... |
