Abstract

NH4H2PO4 as matrix modifier,the trace cadmium was determined by graphite furnace atomic absorption spectrometry.The method is simple,fast,reproducible,high sensitive and accurate.Recoveries are in the range of 87.7%—103.9% with additions of 0.010—0.100mg/kg cadmium.The detection limit is 0.08ng/mL.
