Determination of Selenium Content and Quality of Different Selenium-Enriched Products by Hydride Generation Atomic Fluorescence Spectrometry

摘要

Selenium plays an important antioxidant role and anticancer in the body. The ability to enrich selenium in different organism and the qualities of these products are still rare. Concentrations of selenium in different selenium-enriched products were ditermined by hydride generation atomic fluorescence spectrometry. The results showed that purple potato is lower than standard and other three products are higher than standards. So selenium-enriched products should be strictly tested before entering the market.
