Abstract

V originále

In the elimination voltammetry with a linear scan rate (EVLS), elimination of the selected particular currents from the linear scan voltammetry results is achieved by an elimination function formed by a linear combination of the total currents measured at different scan rates.Theoretical curves of an irreversible current with adsorbed substance being electroactive were calculated for three elimination functions: A - the function eliminating Ik and Ic and conserving Ir , B - the function eliminating Ic and Ir , conserving Ik , and C - the function eliminating Ir and Ik and conserving Ic, where Ic , Ir , and Ik are the charging current, the reversible diffusion current, and the kinetic current, respectively. A larger difference between diffusion and adsorption was exhibited by the elimination function A. It provides a substantial increase in resolution and sensitivity as compared to the linear scan voltammetry current peak and clearly marks the adsorption.
