Research on the Chloride Treatment from Desulphurization Wastewater by nano-TiO2
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.
