Abstract
The essay develops a new method of microwave degestion with a sample of ICP - AES si-multanuously determining Mg, Al, Fe, Pb, Cr, Ni, Mn and As eight trace elements. The detection limits of the method is 0. 002 - 0. 036μg/mL .The recycling rate ranks from 92.8% to 107.6% . RSD is less than 3. 19% . This method is accurate, quick - acquired and convenient. It is used in the determination of granite with the result is satisfactory.
