[Study on the direct determination of Pb and Cd in milk powder by GFAAS].
The paper reports the direct determination of Pb and Cd in milk powder by GFAAS. The mothed does not need any pre-treatment to the samples and fully use some function of pre-treatment which the Graphite Furnace have. The result indicates that the method is simple, rapid and accurate, and the false result from any pre-treatment to the samples can be reduced. The recover rate of Pb is 100.1%, CV =2.7 ; and Cd is 98.6%, CV = 3.1 %. This method is also applied to the rapid determination of Pb and Cd in soluble samples with satisfactory results.
