摘　　要：本实验用Fe_(3)O_(4)-蛭石复合材料作为吸附剂,研究不同的反应温度、pH值、复合材料添加量、反应时间条件下,Fe_(3)O_(4)-蛭石复合材料对Cr^(6+)的吸附效果的变化。由实验结果可知,采用Fe_(3)O_(4)-蛭石复合材料对Cr^(6+)进行吸附时,复合材料添加量不应过多或过少;复合材料在短时间内(0.5 h)即可对Cr^(6+)的吸附取得很好的效果;一定范围内,高温、高pH值有利于提高复合材料的吸附性能。The purpose of this experiment is to study the adsorption performance of Fe_(3)O_(4)-vermiculite composite for Cr^(6+).In this experiment,Fe_(3)O_(4)-vermiculite composite material was used as adsorbent to study the change of adsorption performance of Fe_(3)O_(4)-vermiculite composite material to Cr^(6+)under different reaction temperature,pH value,addition amount of composite material and reaction time.The results of this experiment show that when Fe_(3)O_(4)-vermiculite composite material is used to adsorb Cr^(6+),the addition amount of composite material should not be too much or too little.The composite material can adsorb Cr^(6+)in a short time(0.5 h)and achieve good results.In a certain range,high temperature and high pH value are conducive to the adsorption performance of the composite.
