含汞废水主要来源于有色金属冶炼厂、化工厂、农药厂、造纸厂、染料厂及热工仪器仪表厂等。大孔巯基离子交换剂对含汞废水处理有很好的效果。树脂上的巯基对汞离子有很强的吸附能力吸附在树脂上的汞 ,可用浓盐酸洗脱 ,定量回收。含汞废水经过处理后排出水含汞量可降至 0. 05mg/L以下。此外 ,采用选择吸附汞的螯合树脂处理含汞废水也正在推广应用。并取得了一定效果。在大部分无机汞的离子交换处理技术中 ,首先需加入氯气或次氯酸盐或氯化物 ,以形成带负电荷的汞氯络合物 ,然后用阴离子交换树脂脱除。离子交换法主要用于处理背景氯化物含量较高的工业废水。一些处理数据表明 ,先经初步处理再用离子交换法进行二级处理所得到的离子交换效果最佳。
Tulsion®CH-95 是一款为了从工业废水中去除回收汞和贵金属而专门开发的螯合树脂。
Tulsion®CH-95 是一款拥有聚乙烯异硫脲官能基的大孔树脂,这种树脂对汞有极高的选择性。它也选择其他的贵金属,如黄金,铂金和其他铂金族金属。钠,碱土,铁铜等重金属等是不能干扰其对汞和贵金属的选择去除回收的。
