Title: Voltammetric analysis of some carbamate pesticides
Abstract: The electrochemical activity of 13 carbamate pesticides has been investigated in the potential range of a glassy carbon electrode, over a pH range from 2.5 and 10. Four compounds, pirimicarb, methiocarb, aminocarb and zectran, give oxidation waves; however, only those for aminocarb and zectran are suitable for analytical electrochemical detection in association with high-pressure liquid chromatography. The oxidation reaction has an ECE mechanism, proposed to involve formation of a carbamate cation radical. This hydrolyses to form a phenol which is in turn oxidized, the end product being a substituted dimethylamino-benzoquinoneimine.
