Open publisher page 0 citations

Abstract

A method for the continuous determination of Pb and Cd in feed by flame atomic absorption spectrometry (FAAS) was developed with high sensitivity and fine accuracy.Preconcentration and extraction are not necessary for the determination,so the method is rapid and easy to operate.The recoveries for Pb and Cd are in the ranges of 95.0%—105.0% and 94.0%—98.0% with the relative standard deviation of 0.48%—1.40% and 2.56%—3.50%,respectively.
