%X 论文选用稻壳作吸附材料处理孔雀石绿模拟废水。借助SEM、BET和FTIR等手段对稻壳结构、形貌和特性进行表征&#65292;采用静态吸附实验探究了吸附时间、吸附剂投加量、孔雀石绿初始浓度和温度等因素对吸附效果的影响&#65292;并用动力学模型和吸附等温模型进行拟合分析。SEM可以明显观察稻壳呈现纤维状或蜂窝状多孔结构&#65292;BET结果表明稻壳的比表面积为0.8064 m<sup>2</sup>/g。孔雀石绿在稻壳上的吸附符合Langmuir模型&#65292;说明孔雀石绿在稻壳的吸附为单分子层吸附。动力学拟合结果证明稻壳对孔雀石绿的吸附符合准二级动力学模型&#65292;以化学吸附为主导。<br>The paper uses rice husk as an adsorbent material to treat simulated wastewater containing malachite green. The structure, morphology, and characteristics of rice husks were characterized using SEM, BET, and FTIR techniques. Static adsorption experiments were conducted to investigate the effects of adsorption time, adsorbent dosage, initial concentration of malachite green, and temperature on the adsorption efficiency. Dynamic and adsorption isotherm models were fitted and analyzed. SEM can clearly observe the fibrous or honeycomb like porous structure of rice husks, and BET results show that the specific surface area of rice husks is 0.8064 m<sup>2</sup>/g. The adsorption of malachite green on rice husks conforms to the Langmuir model, indicating that the adsorption of malachite green on rice husks is a monolayer adsorption. The dynamic fitting results demonstrate that the adsorption of peacock green by rice husks follows a quasi second order kinetic model, with chemical adsorption as the dominant mechanism.
