The dj technique, the matrix-effect correction technique, which has been published as the JIS method for iron and steel analysis by XRF (JIS G-1256), was applied to analysis of electrolytic Zn-Fe alloy-plating solutions.
The feature of this technique is that an estimated binary calibration curve is prepared for Fe i-component binary alloy system. The assumed calibration curve to analize i-component can be universally applied free from any matrix effect of sample. H2O-Metal binary solution system, however, cannot be prepared due to insolubility of metal in water.
Then, the analytical measurements have been made on a variety of H2O-Metal-SO4 ternary system solutions to obtain an assumed calibration curve for H2O-Metal binary solution.
dj values for each component coexisting in the electrolytic plating solution could be calculated by multiple regression analysis.
In an attempt to analize Zn concentration in H2O-Zn-Fe-K-SO4-NH4 multi-component solutions, the present method showed good agreement with the chemical method within 0.45 g/l (σ) over the range of 430 g/l Zn.
