摘要
本文利用氢化物发生-原子荧光光谱法分析技术测定土壤中的总汞,样品用(1+1)的王水试剂在沸水浴中加热消解,最后经离心分离处理,取上清液待测。该方法检出限为0.002μg/kg,测定上限为0.400 mg/kg。
Hydride generation-atomic fluorescence spectrometry method is used to analyze total mercury in the soil.Treat the sample with（1＋1） aqua regia reagent firstly,and then heat and decompose it in the boiling water bath.Finally,clarify the liquid through centrifugal separation and fetch the upper supernate for determination.The available concentration for determination of the method is from 0.002μg /kg to 0.400 mg/kg.
