[Determination of cadmium in tea by GFAAS].
A method for the determination of cadmium with platform graphite furnace atomic absorption spectrometry was studied with PdC12 and Mg(NO3)2 as matrix modifier. The method is simple and accurate, and can eliminate the matrix effecte. It can be applied to directly determine cadmium in the tea sample.
