Elimination Voltammetry - Modern Electroanalytical Method for Resolution of Overlapped Voltammetric Signals

Popis výsledku v původním jazyce

The elimination voltammetry with linear scan (EVLS) was used to study adenine and cytosine reduction signals at the mercury electrode. In comparison with the linear scan voltammetry providing only one unresolved peak, two elimination functions provide good resolution of individual peaks and significant increase of sensitivity. The first elimination function eliminates the kinetic current ( ) and conserves the diffusion current ( ). The second elimination function eliminates kinetic and charging currents( and ) simultaneously and conserves the diffusion current ( ). Both functions give two well resolved peaks of adenine and cytosine in a wide concentration range, while the linear sweep voltammetry gives badly resolved peaks due to the hydrogen evolution. The best resolution of peaks is observed in acetate buffer at pH 3.8 and a detection limit for both substances is 500 nM. The concentration dependence of EVLS peak heights for one substance at the constant concentration of the other su
