TY - JOUR ID - 390892 AU - Trnková, Libuše - Friml, Jiří - Dračka, Oldřich PY - 2001 TI - Elimination Voltammetry of Adenine and Cytosine Mixtures JF - Bioelectrochemistry VL - 2001 IS - 54 SP - 131 EP - 131 PB - Elsevier SN - 15675394 KW - Elimination voltammetry with linear scan KW - cytosine KW - adenine KW - reduction of bases KW - hydrogen evolution N2 - 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.Two selected 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 substance is linear. The peak potentials differ in these elimination functions. The difference in EVLS peak potentials gives the possibility to evaluate .EVLS contributes to the resolution of cathodic signals of purine and pyrimidine bases at very negative potentials near supporting electrolyte discharge.
