摘要：

Paraquat (1,1'-dimethyl-4,4'-bipyridinium dichloride) is extensively used as a weedicide and the resulting water contamination is a potential health hazard. It is found that paraquat can be mineralized to CO2, NH3, HCl and small quantities of NO2-/NO3- by solar or artificial irradiation of contaminated water in the presence of TiO2-coated polythene or polypropylene films.
