Method of Elements Identification in the Multicomponent Signal

Abstract

To measure concentrations of toxic elements in analytical systems of ecological monitoring, a generative model of a multicomponent differential signal of stripping chronopotentiometry is used in the coordinates of potentials in time (е, dt/dе) in the form of a model of the capacitive background discharge of electrodes (base curve) and the sum of the models of the stripping components of chemical elements, given by asymmetric normal distribution functions. Identification of elements with slight overlapping of component signals is carried out based on the maximum value and range in which potentials change.
