| Abstract: | To establish a method of determination of aluminum in spirulina powder by GFAAS.The samples were dissolved with microwave digestion and determined by GFAAS.Mg(NO3)2-NH4H2PO4 were used as the martrix modifier to reduce the interference.Analytical conditions for determiantion were optimized.Result: The detection limit of this method was found to be 1.52 μg/L and the relative standard deviations were between 2.13%～6.29%.Value of recovery found were in ranges of 90.65%～108.15%.The method of determination is simple,rapid and the analytical results meet the demands of accuracy and precision. |
