Microwave digestion/ ICP-AES method was adopted for the determinations of K、Na、Ca、Mg、Fe、Mn、 Ni、Cr、Zn、Cu、Pb、Cd in bean-product.The detection limit of each element is from 0.003 to 0.043 mg/L,the relative standard deviation is from 0.74% to3.27%,and the recovery ratio of spiked sample is from 97.8% to 105.3%.These results showed that the microwave digestion combined with ICP-AES is a sensitive method for the determination of elements in bean-product.
