| 摘 要： | 研究了硼氢化钾还原－原子荧光光谱法测定进口涂料中汞，在最佳条件下，荧光强度与汞浓度在0－20ng/mL范围内呈线性关系，相关系数为0.9998，检出限为0.04ng/mL。用本方法测定溶剂型涂料中的汞，回收率为94.4%-101.0%，相对标准偏差为3．62％。方法具有操作简单、快速、准确、灵敏度高等优点，可用于进口涂料中汞的测定。

| Abstract: | Determination of mercury in coatings by potassium borohydride reduction-atomic fluorescence spectrometry has been studied.Under the optimum conditions,there is a linear relationship between the fluorescence intensity and mercury concentration in the range of 0-20ng/mL with correlation coefficient 0.9998.The detection limit is 0.04ng/mL.The proposed method has been applied to the determination of mercury in solvent coatings with satisfactory results.The recovery is 94.4%- 101.0%,and the relative standard deviation is 3.62%.The method is simple,accurate and rapid with high sensitivity.The method has been applied to the determination of mercury in import coatings. |
