Abstract:
      It uses mixed acid to directly digest the samples, without separating residual silicon. It directly dissolves the residuals into the solution, uses inductively coupled plasma - atom emission spectrum (ICP-AES) to determinate the high content silicon in aluminum alloys. It employs matrix match method to prepare standard solution series. The deviation of test result to the standard is within 0.3%, with recovery rate within 95~105%. The method simplifies the treatment of samples. It is applicable to rapidly and efficiently determinate high content silicon in aluminum alloys.
