Abstract: Catalytic activation is necessary for solar photodegradation of dyes in textile industry wastewater treatment, and TiO_2 could be used for this purpose. Changing the size of titanium oxide and doping it with metals like Sn(IV) can also improve its catalytic behavior. The results of this study showed that solar degradation of acid orange 7 in the presence of nanosized particles as a catalyst is possible within 1 h of radiation.
