Photocatalytic Degradation of Lindane in Aqueous Solution

Photolysis of lindane in aqueous solution, using near‐visible and UV light (λ >320 nm) and in the presence of the polyoxometallate PW12O403‐, results in its conversion to CO2 and HCl. Initial photodecomposition takes place within a few minutes both in the presence and absence of dioxygen. The effective mineralization in the absence of dioxygen suggests that OH radicals act as the primary oxidant in this case.
