摘要
建立了利用农林废弃物猕猴桃皮吸附重金属铬(Cr~(6+))的方法。探讨了猕猴桃皮改性方法、pH、吸附时间、温度、吸附材料投加量及Cr~(6+)初始浓度等对吸附性能的影响。吸附过程通过Freundlich和Langmuir吸附等温模型描述,结果表明,改性猕猴桃皮对Cr~(6+)的吸附符合Freundlich吸附模型。
A method for adsorbing heavy metal chromium(Cr~(6+)) from kiwifruit skin was established. The effects of modification method, pH, adsorption time, temperature, adsorption material dosage and initial concentration of Cr~(6+) on the adsorption property of kiwifruit skin were discussed. The adsorption process was described by Freundlich and Langmuir adsorption isotherm model. The results showed that the adsorption of Cr~(6+) by modified kiwi skin was consistent with Freundlich adsorption model.
