Abstrakty
W niniejszej pracy została przedstawiona technologia elektrochemicznego nakładania warstw polianiliny (PANI) na elektrody złote oraz pomiary analityczne stężenia kwasu askorbinowego (AA) w buforowanym roztworze wodnym wykonane metodą woltamperometrii cyklicznej i chronoamperometrii z wykorzystaniem elektrod złotych i Au/PANI. W przypadku czujników z elektrodami pracującymi - Au/PANI, sygnał analityczny był znacznie wyższy od sygnału analitycznego uzyskanego za pomocą elektrod złotych, a potencjał prądu piku utleniania znacznie niższy.
This paper describes the technology of electrochemical deposition of polyaniline (PANI) layer on gold electrode, and the analytical determination of ascorbic acid (AA) in buffer solution by cyclic voltammetry and chronoamperommetry with fabricated gold and Au/PANI electrodes. In the case of sensors with Au/PANI electrodes, analytical signal was much higher then for the bare Au electrodes, while the oxidation potential peak was much lower.
