| Abstract: | It is reported in this paper that microamounts of lead is first extracted by APDC in MIBK, and then it is determined by FAAS directly in the organic phase. The method has been applied to the analysis of cakes and some other foodstuffs. The sample is treated by dry ashing. The average recovery obtained is 98. 7% with a RSD less than 4.4%. |
