【摘要】 研究了澳洲坚果壳活性炭对重金属离子Cr(Ⅵ)的吸附特性.结果显示:该活性炭对Cr(Ⅵ)的吸附受pH值、振荡时间、温度等影响,且Langmuir等温方程和Freundlich等温方程都能很好地描述澳洲坚果壳活性炭对Cr(Ⅵ)的吸附,其吸附主要为单分子层的物理吸附.更多还原

【Abstract】 The absorptive properties of activated carbon,which obtained from macadamia nut shell,were investigated.The results show the activated carbon exhibits effective adsorption for Cr(Ⅵ),and the absorptive properties were influenced by the pH、time and temperature.The adsorption curve is in accord with Langmuir isothermal equation and Freundlich isothermal equation,with single molecular model.更多还原
