| 摘 要： | 通过改变不同的吸附条件,研究了钠基膨润土对水相中锌离子的吸附特性。实验结果表明,钠基膨润土对Zn2+有较好的吸附作用;在固液比为6g/L时,pH=8时,温度为20℃,吸附时间为120min时,吸附率达到96.71%。膨润土对Zn2+的吸附符合Langmuir吸附模型。

| Abstract: | The adsorption characteristics of Na-bentonite for the aqueous zinc ion under the different experimental conditions were studied.The results showed that Na-bentonite had better adsorption capacity for zinc ion,when the solid-liquid ratio was 6g/L,pH value 8,the temperature 20℃,and the adsorption time 120min,and the adsorption rate reached 96.71%.The adsorption of Na-bentonite for zinc ion was consistent with Langmuir adsorption model. |
