摘要
实验采用DMA-80直接测汞仪直接测定水及土壤中的痕量汞,方法在0-400 ng范围内线性良好,最小检出量为0.02ng,加标回收率为97.8%~104.2%。方法操作简单,灵敏度高,结果准确。
In this paper,the trace mercury in water and soil was directly determined with DMA-80 direct mercury analyzer.The results showed the good linearity was in the range from 0 to 400 ng.The detection limits was 0.02 ng.The spiked recoveries were between 97.8%and 104.2%.The technique is easy to use with high sensitivity and accuracy.
