Determination of ascorbic acid by polypyrrole potentiometric detector in ion chromatography
Şahin, Mutlu; Özcan, Levent; Usta, Betül; Şahin, Yücel (Elsevier Advanced Technology, 2009)A potentiometric detector, based on electrodeposition of polypyrrole onto Pt electrode, was investigated in this study. The chromatographic performance of the PPy detector was investigated in ion chromatography. The resulting ... -
Electrochemical polymerization of fluoro- and chloro-substituted anilines and copolymers with aniline
Şahin, Y; Percin, S; Şahin, Mutlu; Özkan, G (John Wiley & Sons Inc, 2004)Poly(2-fluroaniline) and poly(2-chloroaniline) were synthesized by an electrochemical method in an acetonitrile solution containing tetrabutylammonium perchlorate and perchloric acid. Also, the electrochemical copolymerization ... -
Electrochemical preparation of a molecularly imprinted polypyrrole-modified pencil graphite electrode for determination of ascorbic acid
Özcan, Levent; Şahin, Mutlu; Şahin, Yücel (Molecular Diversity Preservation Int, 2008)A molecularly imprinted polymer (MIP) polypyrrole (PPy)-based film was fabricated for the determination of ascorbic acid. The film was prepared by incorporation of a template molecule (ascorbic acid) during the ... -
