摘要
目的研究氢化物原子荧光光谱法测定食品中铅。方法采用微波消解作食品样品前处理方法，用氢化物发生原子荧光光谱法检测食品中铅。结果铅的．测定线性范围为0～80ng／ml，方法的相对标准偏差为2．32％，回收率为92．0％～102．O％。结论氢化物原子荧光光谱法准确，干扰物质少，与石墨炉原子吸收光谱法测定结果相一致。
Objective To determine lead in food samples by hydride generation atomic fluorescence spectrometry. Methods A microwave dissolution combined with hydride generation atomic fluorescence spectrometry method was developed to determine lead in food samples, Results The linear range was 0 - 80 ng/ml, the relative standard deviation was 2.32% and the recovery rate was from 92.0% to 102.0%. Conclusion The method is accurate with little interference,
