| Abstract: | A method was established for simultaneous determination of As,Cd,Cr,Hg Ni and Pb by ICP-AES with microwave-assisted digestion.Microwave-assisted digestion conditions were optimized and effects of concomitant ions were studied.This method is efficient,facilitated and accurate.The recoveries rate of this method were between 80.0% and 103.3%,while relative standard deviation was lower than 6.8%. |
