Özet:

 

The reduction behavior of fenoxaprop-p-ethyl (FNX) was studied on a hanging  mercury drop electrode. FNX showed 2 reduction peaks at about --0.7 V and at  about --0.9 V versus Ag/AgCl/3.0 M KCl in Britton--Robinson buffer at pH  4.8. 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. The linear working  range was established as 0.30--15.0 m M. Limit of detection and limit of  quantification were calculated as 0.07 m M and 0.24 m M,  respectively. The proposed method was successfully applied for the  determination of FNX in tap water, river water, and plant samples with  recoveries between 95.7% and 99.6% showing a relative standard  deviation of less than 15%.
