Abstract :
Electrochemical activation of solutions is employed in many technologies connected with aqueous and non aqueous solutions, for example, in agriculture, in oil production, in medicine. Solutions of electrochemical activation are also employed for intensification of sample pretreatment in analytical chemistry, for example, the method of electrochemical sample pretreatment (EChPt) of aqueous solutions in stripping voltammetry (SVA). The improvement of reproducibility of anodic signal of element, linearity of calibration curves of aqueous solutions of Cd, Pb, Cu and stabilization of the work of the mercury film indicator electrode were shown in SVA determination. Investigation of reasons of the influence of EChPt on the characteristic properties of the substances is one of the areas of basic researches in analytical chemistry and chemistry of solutions. The purpose of the given work is to research of electrochemical activation of aqueous-salt solutions. Voltammetric signals of Cu, Cd, Pb are used as the test for activating the solution.
