| 摘 要： | 采用二次回归正交旋转组合设计,研究白菜渣对重金属铜离子的吸附作用；建立了吸附率对铜离子浓度、白菜渣加入量、溶液pH、吸附温度及吸附时间5个试验因素的正交回归模型.结果表明:Cu2+浓度50 mg/L、菜渣量0.5g、pH 6、温度20℃、时间4h时,吸附率达最大值Ymax=98.11％.回归模型经显著性检验达显著水平,较好拟合了吸附率与各因子之间的关系.

| Abstract: | The effects of adsorption of cabbage slag on heavy metal ions of brass were studied with the method of thequadratic regression orthogonal rotating combination design.The regression model of adsorption rate was established on copper ion concentration combination,dish slag quantity,pH,temperature,time.The results showed that the of model to infer showed that cabbage residue on adsorption of Cu2+ in the best condition to reach the largest adsorption rate Ymax=98.11% was at a concentration of 50 mg/L,addition of 0.5 g,pH 6,temperature of 20℃,time of 4 h.The regression model established by significant test ascended a significant level,model analyses factors adsorption rate and the relationship between them. |
