General Description

Endosulfan alcohol is a man-made chemical that is derived from the pesticide endosulfan. It is a white crystalline solid that is highly toxic and has been classified as a persistent organic pollutant (POP). Endosulfan alcohol is highly soluble in organic solvents and has low water solubility. It is primarily used as a pesticide to control a wide range of insects on crops such as coffee, tobacco, and cotton. However, due to its environmental persistence and toxicity, many countries have banned or severely restricted its use. Exposure to endosulfan alcohol can cause a range of health effects in humans, including neurological and reproductive problems. Due to its potential harm to both human health and the environment, there are ongoing efforts to phase out the use of endosulfan and its derivative chemicals.

Comparative studies of various iron-mediated oxidative systems for the photochemical degradation of endosulfan in aqueous solution

This study investigated iron-mediated oxidative processes for the photochemical degradation of endosulfan, a chlorinated insecticide and central nervous system disruptor. At UV fluence of 360 mJ/cm2, 52.4% and 32.0% removal of 2.45 μM initial endosulfan was observed by UV/Fe3+ and UV/Fe2+ processes, respectively, at an initial concentration of 17.8 μM iron. The degradation of endosulfan by UV/Fe3+ or UV/Fe2+ was dramatically enhanced by adding peroxide (i.e., H2O2, S2O82- or HSO5-). Among the UV/peroxide/Fe processes, the highest degradation efficiency of 99.0% at UV fluence of 360 mJ/cm2 was observed by UV/HSO5-/Fe2+ with 2.45 μM [endosulfan]0, 17.8 μM [Fe2+]0, and 49.0 μM [HSO5-]0. The observed degradation rate constant of endosulfan was promoted either by increasing [Fe2+]0 and/or [peroxide]0 or by decreasing [endosulfan]0, while the initial degradation rate of endosulfan increased with increasing [Fe2+]0, [peroxide]0, or [endosulfan]0. At UV fluence of 6000 mJ/cm2, 45.0% mineralization as represented by the decrease in total organic carbon content was observed by UV/HSO5-/Fe2+ at 9.80 μM [endosulfan]0, 980 μM [HSO5-]0, and 17.8 μM [Fe2+]0. The major by-product of endosulfan was observed in all cases to be endosulfan ether which was further degraded with an extended reaction time. The results suggest that iron-mediated advanced oxidation processes (AOPs) have a high potential for the removal of endosulfan and its by-product from contaminated water.
