Abstract:

A microwave digestion coupled plasma atomic emission spectroscopy(ICP-AES) method was presented for the determinations of Al, Zn, Cu, Cd, As, Cr and Pb in Porphyra haitanensis, and the samples were collected from a from in east china sea. The recovery rates of metals were between 97.8% and 104.9%, and actual applications demonstrate that this method is sensitive to achieve the determinations of metal content in Porphyra haitanensis. The results showed that an significant increasing trends were found in the metal contamination of Porphyra haitanensis during the past five years(P<0.05, RSD<1.89%), and different tenderness of the Porphyra haitanensis collected in 2012 showed an increasing contaiminations in the first＞the second＞the third＞the fourth cultivation duration.
