Aluminum Determination in the Dried Products of Vegetables by Inductive Coupled Plasma Mass Spectrum

Aluminum in the dried products of vegetables digested by microwave are detected by inductive coupled plasma mass spectrum(ICP-MS).The microwave digestion condition is optimized from digestion system,proportion of acids and digestion procedure.The results show that the method of detection limit is 0.1mg/kg with the relative standard deviations、(RSD,n=6)of 1.40%,and the measured values are almost the same as the national?certified standard substances?.The method is reliable,simple operation,rapid and high sensitivity.
