tailieunhanh - Reduction behavior of fenoxaprop-p-ethyl and its voltammetric determination

The reduction behavior of fenoxaprop-p-ethyl (FNX) was studied on a hanging mercury drop electrode. FNX showed 2 reduction peaks at about – V and at about – V versus Ag/AgCl/ M KCl in Britton–Robinson buffer at pH . Both reductions were irreversible and adsorption was effective. The reduction peaks were assigned to the reduction of C=N to CH–NH and the reduction of C=O to CH–OH. Square-wave voltammetry has been proposed and validated for quantification of FNX in different samples. |
