摘要:
采用DMA-80直接测汞技术,与国标方法原子荧光法对土壤中总汞的测定进行了方法比对研究。试验结果表明,直接测汞法的检出限优于原子荧光法,精密度和准确性能够满足土壤实际样品的测定,对30个实际样品分析结果的比对表明,方法间无显著差异,该方法快速、准确、无污染。

Abstract:
Compared with atomic fluorescence spectrometry (as the national standard method) in determining the total mercury in soil, the DMA 80 direct mercury testing method had a better detecting limit. Precision and accuracy satisfied the requirement of analyzing practical soil samples. Furthermore, there is no significant differences between two methods on the basis of analyzing 30 practical soil samples because of its fast, accurate, non pollution.
