To develop a method on determination of mercury in gold loaded resin material by solid sam-pling-cold atomic absorption spectrometry. The method use Hydra C automatic solid mercury analyzer combined with the application of gold amalgam reduction catalysis and enrichment technology. Mercury standard solution in the 0. 0 ~ 100. 0 ng / mL concentration range was a good linear relationship,the re-gression coefficient r = 0. 999 5,the detection limit was 0. 2 μg / kg,measured relative standard deviation was 1. 94% ,and with atomic fluorescence comparison,the two methods was no significant difference. The method is simple,rapid,sensitive and suitable for the detection of mercury in gold-resin content.
