摘要
以风化煤为腐植酸原料,用直接测汞仪测定腐植酸对水体中金属汞的吸附,研究最佳吸附条件.试验结果表明,在反应时间为20 min、改性腐植酸与污水比为10:1、p H值为3时,腐植酸对总汞吸附率可达95%以上.在最佳吸附条件下,对实际样品进行吸附处理,吸附率大于94%,由此可见,腐植酸对汞污染的水体具有显著的净化效果.
Adsorption of humic acid in water of mercury was determined by Direct Mercury Analyzer. Optimum adsorption conditions were recived. The experiment results showed that mercury removal rate was up to 95 %,when contact time is 20 min, the ratio of humic acid to mercury pollution of water is 1：10 and p H=3. Under the best conditions of adsorption,the actual samples were processed and the adsorption rate is greater than 94 %. It showed that the humic acid on mercury pollution of water has significant effect.
