Analysis of Electroplating Solution and Adhesion of Electric Heating Tube by X-ray Fluorescence Spectroscopy

Recently, technological progress has been very significant in all fields of the industry, with a strong trend towards high value-added materials from the perspective of raw materials. Among them, coating materials, in particular, can improve the corrosion resistance, mechanical and electrical properties of materials, and many research institutes and institutions have conducted research on them. Therefore, the analysis of electroplating solution and electroplating adhesion requires high speed and accuracy, and the dependence on instrument analysis is also increasing. X-ray fluorescence spectroscopy analysis is a very effective analytical method for analyzing the plating solution and plating adhesion from the perspective of sample pre-treatment. That is, if the filter paper method is used, the electroplating solution can be dropped onto the filter paper for analysis, and the electroplating adhesion amount can be directly analyzed using the plate. Especially for the X-ray fluorescence spectroscopy analysis of electroplating solution, the new filter paper developed by our analysis center can be used for analysis, and its simplicity of use has received attention from the analytical community. Examples of using new filter paper for analysis.

This article introduces analysis examples of Sn, Cu, and Fe in electroplating solutions, as well as examples of C: and Ni as adhesion analysis.

Analysis of Electroplating Solution

The samples were prepared as independent samples of Sn, Cu, and Fe in the electroplating solution, modulated with sulfuric acid to the concentrations shown in Table 1. The sample is dripped with 100t. L of sample solution in a 030mm circle printed on filter paper, and then dried as a drip sample. The time required to prepare 5 drop samples is only about 5 minutes.

Prepare 5 drop samples for the same sample, and the reproducibility results between these samples are shown in Table 2. The accuracy obtained from the working curve is shown in Table 3. From its results, we can know that this analysis method can achieve sufficient accuracy in practical applications.
