阳离子交换树脂富集-流动注射-冷原子荧光光谱法测定环境水样中痕量汞
FI-CV-AFS Determination of Trace Amount of Mercury in Environmental Water After Enrichment with Cation Exchange Resin
摘 要
提出了用阳离子交换树脂富集环境水样中痕量汞,用流动注射-冷原子荧光光谱法测定其中汞的含量。对阳离子交换柱的制备、富集时间、介质及洗脱剂的酸度等分析条件做了试验并予以优化。汞的质量浓度在40 ng·L-1以内与其荧光强度呈线性关系,方法的检出限(3s)为0.13 ng·L-1。应用此法对环境水样进行分析,并以此样品为基体作回收试验,测得汞的回收率在72.5%~101.3%之间。

Abstract
Trace amount of mercury in environmental water were enriched by cation exchange resin, and determined by FI-CV-AFS. Preparation of the cation exchange column and analytical conditions, including time of enrichment, pH of the sample solution and the eluant, etc. were studied and optimized. Linear relationship between the fluorescence intensity and mass concentration of mercury found was in the range within 40 ng·L-1, with detection limit (3s) of 0.13 ng·L-1. The proposed method was applied to the analysis of samples of environmental water. Using these samples as matrixes, tests for recovery were made by standard addition method; values of recovery found were in the range of 72.5%-101.3%.
