选择 如果:农产品产地土壤经王水水浴直接消解,硫脲和抗坏血酸作为还原剂,使用氢化物发生原子荧光光谱法双道同时测定砷、汞元素。结果表明,砷、汞元素校正曲线相关系数分别为0.9997和0.9999。办法检出限砷0.010μg/g,汞 0.002μg/g。加标回收率砷为97.7%~101.4%,汞为97.3%~99.2%。

Abstract: The determination of arsenic and mercury in agricultural soil by hydride generation atomic fluorescence spectrometry with using thiourea and ascorbic acid as reducing agent was introduced. The result showed that the correlation coefficient with calibration curve linearity of arsenic and mercury were 0.9997 and 0.9999 respectively. The detection limits of the method were0.010μg/g for arsenic, and 0.002μg/g for mercury, and the adding standard recovery was between 97.3% and 101.4%.

Key words: Hydride generation atomic fluorescence spectrometry; agricultural soil; arsenic; mercury
