Abstract

The optimization of sample preparation method,the use of indium as internal standard materials ICP-MS determination of aluminum content in dairy products is related to aluminum concentration in the range of 0~160 ng/mL;the regression equation was Y = 0.0693X +0.0125;correlation coefficient of r = 0.9999;recovery ranged from 92.4 to 104.5%,average of 96.7%;sample RSD 6.0%.The method detection limit was 0.1 mg/kg.
