Abstract
The electrochemical behavior of methylparathion under UV irradiation was monitored by polarography in an aqueous medium (pH 6.5) at 254 and 366 nm, and the effects of atmospheric oxygen and TiO2 on methylparathion were also looked at. Dissapearance of the methylparathion and appearance of two major electroactive degradation products were observed. The reaction rate constants for the process ranged from 3.55 × 10−5 to 5.69 × 10−5s−1, and the reaction showed pseudo-first-order kinetics. The methylparathion transformation did not depend on the experimental conditions. Spectroscopic and electrochemical data suggest the presence of p-nitrobenzoic acid as a common electroactive product.
