Study on the adsorption and degradation of industrial wastewater by TiO2-GO composite photocatalyst
In this paper,titanium dioxide-graphene oxide(TiO2-GO)composite photocatalyst was prepared with phosphoric acid,graphite powder,concentrated sulfuric acid and other reagents as raw materials,and industrial wastewater was simulated with methylene blue solutions of different concentrations.By adding the catalyst to industrial wastewater,the adsorption and degradation effects of the synthesized catalyst on industrial wastewater were investigated under different conditions,and the adsorption and degradation effects of the catalyst were quantitatively analyzed by photoreaction instruments,thermogravimetric analyzers and other instruments;the experimental results showed that the synthetic catalyst(TiO2-GO)had good adsorption and degradation effect on various industrial wastewater,and the best adsorption and degradation effect was obtained when the amount of catalyst was 10g·L-1 and the reaction time was 210min under light irradiation.The catalyst is stable in adsorption and degradation of industrial wastewater and can be reused.
