Matrix modifier GF-AAS determination of urinary manganese

Dapeng Yang

Abstract

Objective:To establish a method for determination of manganese in urine by GFAAS.Methods:The sample was diluted directly,using the tube A,Zeeman background correction and measured with graphite-furnace atomic absorption spectrometry.Results:A detection limit was 0.01 ng/ml,recovery rate 91.5%～108.9% and the relative deviation 4.2%～14.1%.Conclusion:The method is simple and nice and can be recommended for the determination of manganese in urine.
