| Abstract: | This paper studies the marine sediment samples pretreatment and extraction of arsenic, mercury and equipment conditions, the current - carrying acidity, reducing agent for the influence of the atomic fluorescence intensity. This method is simple, rapid, high sensitivity, detection limit arsenic is 0.30 μg/L, mercury is 0.05 μg/L, relative standard deviation isl.5 %to9.7 %,1.2%to9.6%, the recovery rate of 92% to 102 %. |
