Open publisher page 0 citations

Abstract

The samples were microwave-assistedly digested with nitric acid-hydrogen peroxide for ICP-AES determination of zinc,iron,magnesium and copper.The RSD was less than 4%,and the spike recoveries were in 97.4%~105.0%.The determination of limits were within 0.764~1.539 μg/L.This method was fast,stable and accurate,and suitable for determination of the 4 microelements in haliotis.
