Abstract

ABSTRACT: Stable voltammetric sensors were fabricated by dropping the guar-containing polyurethane films on a platinum electrode for the non-enzymatic determination of caffeic acid. The voltammetric responses of PU-G-1% toward caffeic acid have a linear concentration range from 1 to 15 mM with a correlation coefficient of 0.9938. The detection limit of PU-G-1% electrode was approximately 0.25 mM. PU-G-1% sensor showed the good sensitivity, selectivity, high R -value, low detection limit, and high reproducibility toward caffeic acid. Therefore, it is claimed that the polyurethane film containing 1% guar can be used as an excellent selective membrane for caffeic acid detection in the presence of interferent molecules.
