摘　　要：建立了微波消解．氢化物发生原子荧光光谱法（HG—AFS）同时测定出口食用甲鱼中As、Hg残留量的方法，并对HG—AFS工作参数及条件进行了优化和选择。As检出限为0．056μg/L，Hg检出限为0．0071μg／L；相对标准偏差As为0．4％（n=11，ρAs=20μg／L），Hg为0．7％（n=11，ρHg=10μg／L）；回收率范围为92％～99％。本法已用于出口食用水生活甲鱼中As、Hg残留量的检测。A method for the simultaneous determination of arsenic and mercury residues in export edible turtles by microwave digestion HG-AFS has been developed. Operation parameters of HG-AFS and experimental conditions were optimized and selected. The detection limits were 0.056 μg/L for As, 0.0071 μg/L for Hg respectively. The RSDs were found to be 0.4% （n = 11,ρAs = 20 μg/L） for As, 0.7% （n = 11,ρHg = 10μg/L） for Hg. The recoveries were in the range of 92% - 99%. This method has the advantages of easy operation, fast speed and sensitivity and it has been applied to the determination of arsenic and mercury residues in export edible turtles with satisfactory results.
