Abstract
According to the selection principle of internal standard elements and the correction coefficient method,Lu and Y internal standard elements were used and the optimal addition amount was determined for the determination of Cr and Ni content in stainless steel materials using ICP-OES internal standard method.However,Lu as an internal standard element has not been reported.Compared with the commonly used internal standard element Y,Lu as an internal standard element has the same or even better effect on improving the linearity of the calibration curve and measuring accuracy than Y.The results show that Lu and Y,as internal standard elements,have an optimal concentration of 2.0 mg/L after addition,which can improve the signal-to-noise ratio of the analyzed elements.The calibration curve has a linearity of over 0.9999,and has the advantages of accurate analysis results,small analysis errors,and stable analysis methods.They are suitable as internal standard elements for element content analysis in stainless steel.关键词
