石墨炉原子吸收法测定鱼中的铅
DETERMINATION OF Pb IN FISH BY FURNACE ATOMIC ABSOPBTION SPECTROPHOTOMETRY
【摘要】 用硝酸和双氧水对鱼肉样品进行微波消解,然后用石墨炉原子吸收分光光度法测定鱼肉样品中铅的含量,测定结果的相对标准偏差为0.023%~0.137%(n=6),加标回收率为83%~105%。
【Abstract】 Pb in the fish sample which was digested in micro-wave oven with HNO3 and H2O2 was determined by furnace atomic absorption spectrophotometry.The relative standard deviations were 0.023%-0.137%（n=6）,the recoveries were 83%-105%.
