Abstract

The condition of simultaneous preconcentration of Pb and Hg by sulfhydryl cotton, the eluting condition, the determination condition of Pb and Hg by hydride generation AFS and the influence of interference elements were discussed. Then, the method for the determination of ultratrace lead and mercury in the underground water was obtained, and the method is sensitive and reliable. The experiment results show that all of the indexes of this method can satisfy the analysis of the underground water.

摘要

探讨了巯基棉同时富集铅和汞的条件、洗脱条件、氢化物发生原子荧光光谱法测定铅和汞的条件以及干扰元素的影响。由此得到了地下水中超痕量铅和汞的测定方法，该方法灵敏可靠。实验结果表明，该方法各项指标均能满足地下水分析的要求。
