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.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.
