摘要
研究了微波消解石墨炉原子吸收光谱法测定番木瓜酱菜中铅的最佳条件 ,方法简便快速 ,检出限为 0 .0 6 8mg·kg- 1(换算到样品中的最终浓度 ) ,RSD为 1.4 %~ 9.6 % ,样品加标回收率为97.7%~ 10 0 .3%。
Conditions for the GF-AAS determination of microamounts of lead in pickled papaya, including the acid-digestion of sample by microwave-heating, the working parameters of the instrument, elimination of the interference of sodium chloride and etc, were studied and optimized. The limit of detection of this method was found to be 0.068mg·kg -1 , RSD′s found were in the range of 1.4%~9.6%, and recoveries were in the range of 97.7%~100.3%.
