摘要
本文介绍了动态冷原子吸收法快速测定地球化学样品中微量汞的方法。本法研究采用了新型的汞蒸气发生器,并对气泡的干扰进行了研究。线性范围为0.2—12ng/mL,标准回收率为97%—106%,相对标准偏差为3.6%,相关系数为0.9997,试验结果表明此方法简便、快速、准确。
The article introduces the method of cold vapour atomic absorption for determination of trace mercury in geochemical samples.In the research,a new generator of mercury vapour has been employed.Also,the effect of air bubble has been studied.The linear range of the concentration covers from 0.2ng/mL to 12ng/mL and the recovery of method is between 97% and 106%.The relative standard deviation is 3.6% and the correlation coefficient is 0.9997.The experimental results have shown this method is simple,rapid and accurate.
