Advanced treatment of wastewater with methyl orange and heavy metals on TiO2,…

Abstract. Dyes and heavy metals represent common, dangerous pollutants, resulting in large quantities in the textile finishing industry. Advanced removal of heavy metals is usually proposed via adsorption and the use of modified fly ash represents a sustainable solution. Photodegradation of dyes using anatase is largely studied and represents a process that can be up-scaled. For wastewater …
