| The methodwasapplied fordetermination oftrace mercury ( Ⅱ ) bythecatalyticspectrophotometry with standard addition to eliminate matrix effect. The method hascharacteristicsofsimple equipment, easy operation, sensitive and correct. Thelinearity ranged from 3.0 × 10 -3 mg/L to 8.0 × 10 -2 mg/L,the recovery from 96.7% to103% , and the relative standard deviation 0.12%. |
