采用静态吸附方法研究了赤泥用量、pH、反应时间和温度对去除废水中镉效果的影响。结果表明，赤泥对镉离子有较好的吸附性能，吸附率达到95.32%。当镉离子初始质量浓度为10 mg/L时，赤泥合适的投加量为1 g/L，反应时间为1 h，温度越高吸附率越高；溶液pH越高吸附率越高，在碱性环境中会发生沉淀作用。

The effects of dosage of red mud,pH,reaction time and temperature on the cadmium removing effective-ness from wastewater by static adsorption method have been studied. The results show that red mud has pretty good adsorption capacity. Its adsorption rate has reached 95.32%. When the initial mass concentration of cadmium ions is 10 mg/L,the appropriate red mud dosage is 1 g/L,and reaction time 1 h. The higher the temperature is,the higher the adsorption rate. The higher the solution pH is ,the higher the adsorption rate. Precipitation occurs in alkaline environment.
