摘　　要：采用Hydra C自动固体测汞仪,结合应用还原催化和金汞齐富集技术,建立了测定载金树脂物料中痕量汞的固体进样-冷原子吸收法。标准汞溶液在0.0~100.0 ng/m L浓度范围内呈较好的线性关系,回归系数r=0.999 5,方法检出限为0.2μg/kg,测定结果的相对标准偏差为1.94%,与原子荧光法比较,两种方法无显著性差异。本法操作简单、快速、灵敏,适用于载金树脂中汞含量的检测。To develop a method on determination of mercury in gold loaded resin material by solid sam- piing-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.
