Abstract

Discussed with the (MWD) for Nitrogen Oxide interference of the mercury determination in wastewater, studied the method of elimination volatile nitrogen oxides rapidly. Optimized the conditions by microwave-digestion hydride generation atomic absorption method for determination of mercury in daily chemical .The detection limit of the method was 0.4μg/L, the lower limit of quantification was 1.2μg/L, the relative standard deviation determined by spiked samples is 1.5% and recovery from 94% to 103%.
