摘要
研究了天然沸石对含Cr3+的重金属废水的吸附与交换。考查了沸石用量,振荡时间,沉降时间,初始浓度,pH值几个条件对铬的去除的影响,并对沸石的饱和吸附量和再生进行了探讨。结果表明,天然沸石对Cr3+有很强的去除效果,并且容易再生。
The adsorption and exchange of Cr^3＋ in chromium - containing wastewater with zeolite are investigated. Several conditions affecting the removal of Cr^3＋ are investigated, such as the amount of zeolite, time of surging and sedimentation, initial concentration of Cr^3＋ and value of pH,Meanwhile, the amount of saturated adsorption and regenerate of zeolite are discussed. The results show that zeolite can strongly affect the removing of Cr^3＋ and regenerate.
