Abstract

Research on treatment for chloride of desulphurization wastewater by nano-TiO₂ is conducted and based on nano-TiO₂ dioxide characteristics of adsorption and photo-catalysis. Some affecting factors on the removal efficiency were also studied, such as different dosage, mixing time, pH value of the solution and light time. The catalysis mechanisms of nano-TiO₂ on chloride removal efficiency were discussed. The optimum experimental condition was determined after optimized screening. The results show that removal efficiency of chloride was 47.9% and that with illumination was 12.4% higher than that no-illumination. The basic mechanism of nano-TiO₂ to desulphurization wastewater purification was discussed by desorption experiment and infrared spectrum analysis. The results may be used to provide a useful basis for further applying nano-TiO₂ to desulphurization wastewater purification in the near future.
