Abstract: 

The chromium plating solution was prepared from Cr (III) salt mixed with a suitable chelating organic agents. The ratio of chelating agent concentration with Cr (III) concentration was selected object of this study before to apply in practice. Amino-acetic acid chelating compound was agent capable to form the complex with the Cr (III) ions but depending on the ratio of these substances present in solution. In this paper, the research was focused on the complexing of amino-acetic acid and Cr(III) ions, evaluation of plating capabilities of the complexes based on determining the reaction rate during scanning, CV. The experiment shows that the complex of Cr(III)-glycine exhibited a excellent compound to use in chromium electrochemical deposition. By this way the optimal Cr (III) and chelating agent concentration were be selected for making decorative chromium plating solution.
