Open publisher page 0 citations

Abstract

This article used the method of microwave digestion-flame atomic absorption spectrometry(FAAS) to determine cadmium in grain.The digestion plan and the parameters of FAAS were optimized and selected.The linear range was 0—8.0mg ? L~(-1),the detection limit was 1.7μg ? L~(-1),and the recovery rate was 95.0%—106.7%.This method is simple,fast,with less reagent consumption and good reproducibility.
