Abstract

The electrochemical properties of folic acid were investigated in pH range 1.0-9.0 by cyclic, linear sweep and adsorptive stripping voltammetry. The compound was irreversibly oxidized at an anodically pretreated boron-doped diamond electrode in one or two oxidation steps, which are concentration- and/or pHdependent. Using square-wave stripping mode, folic acid yielded well-defined voltammetric responses in both 0.1 M perchloric acid and 0.1 M Britton-Robinson buffer, pH 6.0 with limits of detection 0.035 μg/mL (7.93 10-8 M) and 0.14 μg/mL (3.2x10-7 M), respectively, after an accumulation of 120 s at open-circuit condition.

Özet

Folik asit'in elektrokimyasal özellikleri; pH 1.0-9.0 aralığında dönüşümlü voltametri, doğrusal taramalı voltametri ve adsorptif sıyırma voltametrisi ile incelenmiştir. Bileşik, anodik olarak ön-işlem görmüş borkatkılı elmas elektrot üzerinde derişim- ve/veya pH-bağımlı bir ya da iki basamak halinde tersinmez olarak yükseltgenmektedir. 0.1 M perklorik asit ve 0.1 M Britton-Robinson tamponu (pH 6.0) içerisinde karedalga sıyırma formu kullanıldığında açık-devrede 120 s'lik biriktirme sonrası folik asit sırasıyla 0.035 ?g/ mL (7.93 10-8 M) ve 0.14 ?g/mL (3.2x10-7 M) saptama sınırlarında iyi-belirlenmiş voltametrik yanıtlar vermiştir. Yeni geliştirilmiş olan tekniğin pratik uygulanabilirliği, tablet ilaç şeklinin doğrudan analiziyle kontrol edilmiştir.
