Abstract:The large amount of colored substances exist in the sugar mills wastewater that give higher organic load to the effluent. Therefore, a novel study of sugar mill wastewater treatment was carried out under photocatalysis by using a nanocomposite of silver phosphate-iron-graphene oxide-titanium phosphate (Ag3PO4/Fe/GTiP). The catalyst was prepared by simple chemical process with 2% content of Ag3PO4 to Fe/GTiP. The light, catalyst dosage, pH, and scavenger impacts on the decolorization and chemical oxygen demand (COD) removal from the sugar mill wastewater were observed. The highest decolorization and COD removal of 85.02% and 80.3% was achieved under pH-1 by using 50 W visible halogen light at catalyst dosage of 100 mg/75 ml in 200 min. The excellent recycled results were observed up to four cycles. The obtained results proves that this catalyst has high photocatalytic efficiency to treat the sugar mill wastewater.
