First electrochemistry of herbicide pethoxamid and its quantification using electroanalytical approach from mixed commercial product

Silver Integrated with Carbonaceous 2D Nanomaterials as an Electrocatalyst for Reductive Dechlorination of Chloroacetanilide Herbicide

“…Voltammetric response to metazachlor (1.12 mM in 20 mM NaOH) of the electrodes modified by the prepared nanomaterials was investigated using CV. First, higher potential range (-0.2 to +0.6 V vs. Ag/AgCl reference electrode) was chosen to examine a possibility of MZCh to be oxidized 13,24 . Results in figure 4 where the illustrative cyclic voltammograms of GCE electrodes modified with MX_AgNP24, MX, ErGO_AgNP and ErGO are shown suggested the probability of some response to metazachlor at GCE|MX_AgNP.…”

“…To complete the list, it should be noted that the oxidation of chloroacetanilide herbicides on boron-doped diamond electrode was also the identified mechanism employed for their electrochemical determination. 24,25 Silver nanoparticles synthesized on Ni foam and their efficient employment in a bulk electrochemical dechlorination of the chloracetoanilide alachlor were reported, 20,[26][27][28] but without its electrochemical detection. Similarly, silver nanoparticles were synthesized on glassy carbon electrodes and employed for reductive electrodechlorination of chloroacetic acids (CA) in a few studies, 29,30 some of them also investigated dependence of a cathodic (dechlorination) peak height on CA concentration (0-20 mM) and found it to be linear.…”
