| Popis: | The present study is an attempt to identify the photocatalytic degradation products of quinalphos, an organophosphate pesticide, by employing high pressure liquid chromatography (HPLC) and liquid chromatography–mass spectrometry (LC/MS). Preliminary experiments were carried out for the degradation of quinalphos by irradiating the aqueous solution of pesticide in the presence of TiO2/UV light. The residual concentration of quinalphos was estimated by using UV-Vis spectrophotometer and the formation of intermediates was determined by HPLC studies. The effect of the presence of cations and anions on the photocatalytic degradation has been explored. The intermediates formed during the process were separated and identified by using LC/MS. On the basis of identified products, the mechanism of photocatalytic degradation of quinalphos was proposed. |
