Abstract: Layered double hydroxide pillared by Paratungstate Aion, Mg12 Al6(OH)36 (W7O24 )·4H2O, was prepared via anion exchange reaction of the synthetic precursor, Mg4Al2(OH)12 TA·x H2O(TA2-=terephthalate), and W7O246- ion. Trace aqueous organochlorine pesticide, hexachlorocyclohexane, was totally degraded and mineralized into CO2 and HCl by irradiating a suspension of Mg12 Al6(OH)36 (W7O24 )·4H2Oand HCHin the near UVarea. The model and pathway for the photocatalytic degradation of HCHon the Mg12 Al6(OH)36 (W7O24 )·4H2Owere proposed, indicating that the interlayer space is the reaction field, and that photogeneration of OH ·radicals are responsible for degradation pathway.

Key words: Heterogeneous photocatalysis, Layered double hydroxide, Paratungstate A, Organochlorine pesticide, Anion exchange reaction
