Arsenic titanium dioxide | |
removal of arsenic and disinfection of water was held employing heterogeneous photocatalysis with UV (solar radiation) and ferric chloride. The effect of many parameters was studied: pH, time of exposure, concentration of ion Fe (III), concentration of As (III).With the optimized parameters a continuous flow system was implemented. Optimal conditions were: concentration of the impregnating solution 5% TiO2, [Fe (III)]: 15.5 mg / L, [As (III)]: 160 μg / L, exposure time, t: 140 minutes. Achieving removals under Mexican and international (WHO) law, showing a removal of 98% for arsenic and > 99% in disinfection. It was demonstrated that the process of heterogeneous photocatalysis in the presence of iron salts is a good method for oxidizing and removing arsenic from water and disinfection. | |
