【Abstract】 The silver diethydithiocarbamate was synthesized by a simple method in this paper.The synthesized and marketed reagents effected on determination of arsenic were compared.The results indicate that the synthesized was used to determinate arsenic,the reagent blank was decresed and the sensitivity was improved,and the detection limit was cut down.The quality of the synthesized reagent is better than the marketed silver diethyldthiocarbamate.更多还原
