| Abstract: | The present paper described the approach to removal of non-spectrum interference which involves choice of soluble acid for pretreatment of specimen, separation of interferential substance, enrichment of microelements, matching between referential specimen and analytical specimen, ultrasonic atomization, choice of specimen system to be gasified separatedly and determination of optimal operating parameters, and introduced application of ICP-AES to the metallurgical process and to the iron and steel analysis in particular, and in the meanwhile discussed certain technologies benefitial to analysis on the microelements of impurity and rare earth metal in steel such as ultrasonic atomization ,hydride technology and chromatogram ICP-AES technology. |
