Abstract:
Objective:To establish a method for the determination of Cu,As,Cd,Hg and Pb in spirulina health products. Meth-ods:The samples were digested by microwave and determined by ICP-MS. Results: The minimum detection limits of Cu,As,Cd,Hg and Pb was 6. 72,6. 25,3. 12,0. 331 and 8. 78 ng·g-1 , respectively, and showed good linear relationship within respective concentra-tion range (r >0. 999 7) with the average recovery of 110.4%,96.6%,93.1%,102.8%, 101.4% and RSD of 3.2%,4.2%, 2. 5%,2. 9%,3. 0%(n=9), respectively. Conclusion:The method is sensitive, simple and accurate, and can be used to determine the harmful elements in spirulina health products.
