| Abstract: | Determination of Pb in potassium alum by stablized temperature platform AAS method isPresented in this paper. The severe interferences caused by sample matrix can effectivelysuppressed by using (NH_4)_2, HPO_4 as matrix modifier and Zeeman background correction, andreproducible results can be achieved by method noted above, with a recovery rate of 101.1%and detection limit of 10 pg. |
