Hybrid photocatalyst for wastewater remediation

Abstract

The hybrid photocatalyst for wastewater remediation is a composite of rhodamine B and BiOBr. The rhodamine B has a concentration between about 0.1 wt % and about 1 wt % of the overall photocatalyst. The hybrid photocatalyst is made by immersing a BiOBr semiconductor in an aqueous rhodamine B solution to form the hybrid photocatalyst by sorption of the rhodamine B by the BiOBr semiconductor. In use, the hybrid photocatalyst is added to wastewater containing at least one contaminant, such as methyl orange (sodium 4-[(4-dimethylamino)phenyldiazenyl]benzenesulfonate), to form a suspension of the hybrid photocatalyst and the at least one contaminant. The suspension is then exposed to visible to light to form a slurry containing a reaction mixture in the wastewater. The slurry is then filtered to remove the reaction mixture.
