基于单因素法的蛭石对模拟废水中铜离子的吸附性能

Effect of Vermiculite on Copper Ion Adsorption based-onSingle Factor Experiment

文章采用单因素实验研究了投加量、pH值、吸附温度和吸附时间对蛭石吸附铜离子的影响。实验结果表明:当投加量为15%,pH值为7.0,吸附温度为40℃,吸附时间为120 min时,蛭石可实现对铜离子的吸附率为99.5%。

The single factor test was applied to study the adsorption of copper ion with vermiculite.Influence factors included the additive amount,pH value,adsorption temperature and time.The result showed that the optimization adsorption conditions of copper ion were as follows:additive amount is 15%,pH value is 7.0,adsorption temperature is 40℃,adsorption time is 120 min.The adsorption rate of copper ion is 99.5%.
