摘　　要：采用催化分光标准加入法测定复杂组分水样中痕量Hg2+,线性范围为3.0×10-3mg/L^8.0×10-2mg/L,加标回收率为96.7%~103%,相对标准偏差为0.2%。该方法设备简单,操作简便可行,灵敏度、准确度高。The method was applied for determination of trace mercury （ Ⅱ ） by the catalytic spectrophotometry with standard addition to eliminate matrix effect. The method has characteristics of simple equipment, easy operation, sensitive and correct. The linearity ranged from 3.0 × 10^-3 mg/L to 8.0 × 10^-2 mg/L, the recovery from 96.7% to 103% , and the relative standard deviation 0.12%.
