Multicomponent analysis of stripping voltammograms by target transformation factor analysis

摘要

Target transformation factor analysis was studied for simultaneous determination of four simulated stripping voltammograms. A Gaussian function was used to generate synthetic stripping voltammograms. Two programs, SPGRELEP and ELECTTFA, were designed to perform voltammogram simulation and target transformation factor analysis. The method made use of full information of voltammogram and matrix data processing. The ELECTTFA program was used to determine the number of components, to identify the components and to yield a quantitative analysis of unknowns. Experimental results showed the method to be successful.
