Qualitative Identification of Alloys of Precious Metals by Means of Adaptive Changes the Mode Polarization

Abstract:

This article is about adaptive adjustment of reaction conditions in local electrochemical rapid analysis. These conditions include in-situ current correction during pulse chronopotentiogram mesuarements. Optimal values of correction parameters were obtained by steep ascent optimization method. Treatment of gold alloys chronopotentiograms was made by the decomposition modeling method. As a result, application of a probe current adjustment system to chronopotentiometry process allows more than 3-time increase in reproducibility of experimental results. The most significant factors in optimizing the parameters of the proposed system are the slope of the linear regression coefficient of the reaction system.
