摘　　要：分别采用4种不同的方法对化工生产过程中产生的废水进行了消解,消解后的废水分别采用原子荧光测汞仪与冷原子测汞仪测定了其汞含量,并进行了对比分析。结果表明:冷原子测汞仪可直接测定总汞含量,且快捷、简便,较适合样品量大时的快速测定,但原子荧光测汞仪精密度较高。The wastewater produced in chemical production process was digested by four different methods respectively,and the mercury content in the digested wastewater was determined by atomic fluo-rescence mercury analyzer and by cold atomic mercury analyzer respectively.The results showed that cold atomic mercury analyzer could rapidly,simply and directly determine the total mercury content,and was more suitable for the rapid determination of large amount of sample,but the precision of the atomic fluo-rescence mercury analyzer was higher.
