Abstract:
      Lead content in Spirulina and GBW10025 were measured by Graphite furnace atomic absorption method with GB/T 5009.12-2010 as the reference. The results showed that the relationship of the lead element was good(R=0.9995), And the measurement value of the standard sample matched the cetified value of GBW10025. The recovery rate was higher than 92%. At the same time, Pre-treatment of removing acid and selection of matrix modifier were verified to be important. The method is convenient and reliable with accurate data. It is suitable for measuring lead content in Spirulina.
