Photodegradation of Chlorobenzenes in Micellar Aqueous Solutions of Gemini Surfactants

Abstract:

Photodegradation of 1,2,4-trichlorobenzene (1,2,4-TCB) was examined in one kind of Gemini surfactant solution (ethylene dioctadecyl dimethyl ammonium bromide) and two kinds of conventional surfactant solutions (sodium dodecyl sulfate and polyoxyethylene polyoxypropylene ether). Compared with conventional surfactants, Gemini surfactants make up of two identical or different amphiphilic moieties connected by a spacer group. Under UV irradiation at 254 nm, 1,2,4-trichlorobenzene was decomposed in the three micellar solutions, but the photodegradation rate of 1,2,4-trichlorobenzene in the Gemini surfactant solution was 3.54% and 11.81% higher than those in other two conventional surfactant solutions respectively. Thus, the photochemical reactions of chlorobenzenes can be enhanced in Gemini surfactant solutions.
