Abstract
The content of Cadmium was analyzed by platform graphite furnace atomic absorption spectrometry with thiourea -EDTA-NH4H2PO4 as the matrix modifier. The effect of matrix modifier and instrument conditions to cadmium signal was investigated. The proposed method had a detection limit of 0.06 ng/mL. The sample detection limit was 0.19 ng/g.
