“…Therefore, by processing such major interference elements separately, a more accurate matrix effect correction effect will be obtained. At this time, the mathematical correction method can be used, which is characterized by quantifying the interaction between the elements in the matrix and expressing it in various mathematical models, so that various calculation methods can be used to complete the correction of the matrix effect, mainly the correction of the effect between the elements [3][4][5]13]. Matrix effect correction adopts multivariate statistical analysis of empirical coefficient method, and the established mathematical model is as follows:…”

The content of Mn, Co, and Ni in the ternary cathode material mixture of lithium batteries directly affects the electrochemical performance of the electrode material. The rapid measurement of the content of Mn, Co, and Ni is of great significance to the production and process control of the ternary cathode material. In this paper, energy dispersive X-ray fluorescence analysis (EDXRF) was used to analyze the content of Mn, Co, and Ni in the ternary cathode material mixture of lithium batteries. When calculating the peak area, the branch ratio subtraction method is used to correct the interference of the K β peak of Co on the K α peak of Ni. In the spectrum data processing, combining the advantages of the SNIP method and the polynomial fitting method to subtract the scattering background, the two methods are combined to process the measured spectrum lines, and good results have been achieved. In the matrix effect correction, by comparing the theoretical mass absorption coefficient and the experimental results, it is concluded that the Mn, Co, and Ni in the ternary cathode material mixture of the lithium battery are affected by the matrix effect, which is established by the multiple regression analysis in the empirical coefficient method. Mathematical model to correct the absorption enhancement effect of Mn, Co and Ni. The experimental results show that the average absolute error of Mn, Co, and Ni content in the ternary cathode material mixture of lithium battery using the empirical coefficient method is 0.09%, 0.02%, 0.04%, and the average relative error is 0.52%, 0.12%, 0.13%. Single sample analysis only needs 200s, which meets the requirements of fast, efficient and accurate analysis.

“…Considering all these facts, as reviewer, I would suggest that it might be a better option to dilute the U samples and analyse them using a limited calibration range up to 20 mg mL À1 , especially to achieve better sensitivity and precision for this type of measurement. Biswas et al 219 demonstrated an EDXRF method for the determination of Fe in uranium. The effect of various parameters such as the variation of matrix concentration, detection limit, accuracy, precision, compared with other established methods was investigated.…”
