Removal of procion orange from wastewater by adsorption on waste red mud
The ability of waste red mud, an industrial by-product produced during the processing of bauxite ore, to remove procion orange was investigated at different initial dye concentrations, agitation time, adsorbent dosage, and pH. Adsorption followed the Freundlich isotherm model. A maximum removal of 82% of the dye was observed at pH 2.0. Desorption studies showed that maximum desorption occurred at a pH of 11.
