Photosonochemical decomposition of aqueous 1,1,1 -trichloroethane

This study describes development of 1,1,1-trichloroethane removal from aqueous solutions. The decomposition of aqueous 1,1,1-trichloroethane is more extensive with combined photolysis and sonolysis process than each separately. The extent of decomposition is measured by gas chromatograph for removal of CCl3CH3, by a turbidometric procedure for production of chloride ions, and Fourier transform infrared spectroscopy for solid product. The concept is to degrade CCl3CH3 in water flow systems to chloride ions, which are removable by ion-exchange column. (author)
