Use of the TiO2-UV System to Detoxify Water Contaminated by Lindane (1α, 2α, 3ß, 4α, 5α, 6ß-Hexachlorocyclohexane)
Lindane is a common soil insecticide. Despite its low solubility, it is found in groundwaters which are used as sources of drinking water at some sites. Therefore, it is a pollutant of great concern as it may reasonably be anticipated to be a carcinogen. Its destruction by various oxidants has been studied and lindane has been found to be recalcitrant to many of them, with the exception of the O3-H2O2 combination. Consequently, it was deemed of interest to investigate its elimination by the TiO2-UV system which is an efficient “advanced oxidation technology” (see Ref.) and is now commercialized. Our study was particularly focused on the identification of the degradation intermediates.
