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...
