| Abstract: | The samples were melted with mixed fluxes of anhydrous sodium carbonate and boric acid at high temperature,dissolved by diluted hydrochloric acid,and the content of aluminum in aluminum deoxidizer was determined by ICP-OES.The experimental conditions including instrument parameters and interference of matrix were optimized.The results of experiments proved that matrix matching was used to eliminate matrix interference,which ensured the measurement accuracy and precision.The analytical results were in good agreement with the chemical titration values.The method is rapid,accurate and reliable,and can meet the needs of production and research in determination of aluminum. |
