Abstract
This research work dealt with the electrochemical behavior and voltammetric analysis of
monuron, a phenyl urea herbicide. The sensitive enhancement of the monuron electrochemical
signal, using a pre-activated carbon paste electrode, and the explanation of its mechanism
were the main findings of this study. Unlike most used herbicides (linuron, diuron, fenuron,
etc), monuron was rarely studied before by electrochemical methods. Indeed the square wave
voltammetry allowed to optimize and to analyze monuron in water samples; the results
showed two linear ranges of concentration: from 1.98 to 0.39 µg mL-1 and from 0.35 to 0.08
µg mL-1, with detection and quantification limits of LOD= 0.016 µg mL-1 and LOQ= 0.054µg
mL-1 respectively. Besides these quantitative results, the anodic oxidation of monuron has
been explained by an irreversible adsorption-controlled process, following a “one electron –
one proton” mechanism
