流动注射-氢化物发生-原子荧光光谱法测定土壤中铅

To Detect Lead in Soil by Flow Injection-Hydride Generation-AtomicFluorescence Spectrometry

采用流动注射-氢化物发生-原子荧光光谱法测定土壤中的铅，工作曲线线性关系良好，检出限为0．25mg／kg，相对标准偏差〈3．5％，加标回收率为93．0％～105％。该方法简便快速，测定结果准确可靠。

To detect Lead in soil with flow injection （FI）-hydride generation-atomic fluorescence spectrometry（HG-AFS） was posed. The detection limit of this method is 0. 25 mg/kg, the recovery rate was between 93.0% to 105% , relative standard deviation was less than 3.5%. The method is simple and rapid with satisfactory results.
