  • Abstract A bienzymic sensor for the determination of dithiocarbamate fungicides was developed based on aldehyde dehydrogenase inhibition. The NADH formed by the oxidation of propionaldehyde by aldehyde dehydrogenase was reoxidised by diaphorase using hexacyanoferrate(III) as electron acceptor. The hexacyanoferrate(II) produced was electrochemically oxidised at a potential of 250 mV vs. SCE. As dithiocarbamate fungicides inhibit aldehyde dehydrogenase, a decrease of the induced current was… CONTINUE READING
