Abstract: To explore the altar of the rapid detection Porphyra haitanensis metal elements,a new method for analyzing the contents of metallic elements,such as As,Cd,Cr,Hg,Pb,and Zn in Porphyra haitanensis by inductively coupled plasma-optical emission spectrometry (ICP-OES) was developed. Three representative areas were chosen at Qidong(Jiangsu Province),Xiangshan (Zhejiang Province),and Fuding (Fujian Province) to collect the samples. The samples processing procedures involve two steps,being first decomposed by standing digestion,and then by microwave digestion at different temperature gradient (100 ℃,180 ℃,100 ℃) each for 10 minutes. Standard curve method was used as quantification of samples;the interference was eliminated by the digestion solvent. This method showed satisfactory precision and accuracy with the relative standard deviation(RSDs) between 0.35% and 5.14%. The recovery rates of As,Cd,Cr,Hg,Pb and Zn were between 95.8% and 105.3%,89.0% - 98.0%,93.0% - 103.2%,90.5% - 96.0%,86.5 % - 107.5% and 94.7% - 98.4%,respectively. Survey also found that the Cd in Qidong the content is 3.57 mgkg-1,Pb level 2.15 mgkg-1;Xiangshan in the sample Hg content is 1.54 mgkg-1;a sample of Zn in Fuding the content is 161.12 mgkg-1,from metal content were exceeds bid badly.
