Abstract

The possibility and conditions of the inversion voltammetric estimation of antimony on the basis of different in nature and concentration background electrolytes or buffer solutions are shown and optimized. It is established that the elaborated method can be applied in the analysis of modeled binary, triple, and more complex mixtures as well as of real natural objects and industrial materials. In all cases the elaborated inversion voltammetric method is evaluated by metrological procedure, and the relative standard deviation (S r) is no more 0.129.
