摘　　要：用稻壳吸附剂对甲基紫、孔雀绿、维多利亚蓝三种染料废水进行吸附实验,研究了室温条件下染料溶液pH值、稻壳吸附时间、染料初始浓度等因素对吸附效果的影响。在室温条件下稻壳对三种染料具有较好的吸附脱色效果,当pH=6时脱色率最高;稻壳对三种染料的吸附符合准二级反应动力学模型,较好符合Langmiur等温线方程。The adsorption experiments were researched by using the rice husk as the adsorbent to remove methyl violet, malachite green, vitoria blue from aqueous solution. Effects of initial pH, adsorption time, and initial concentration on dye removal at room temperature were analyzed. It showed that the rice husk had good effect on adsorption and decoloriza- tion of three kinds of dyes. The dye removal had the highest value when pH = 6. The processes of adsorption could be described by an equation of pseudo 2nd - order mode. The processes of adsorption also fitted to Langmiur isotherm equation.
