Removal of Methylene Blue Dye in Aqueous System Using Polyvinyl Alcohol and Chemically Modified-Aluminium Foil Blend

Abstract

Aqueous solution containing different concentrations of methylene blue dye was treated with chemically modified aluminium foil/PVA blends. There have been impressive decolourisation of the dye molecules in the aqueous system treated with the blends. Contact time and amount of composite facilitate more decolourisation of the dye solution. 97 % dye removal has been recorded at optimum conditions of the experiment. Energy dispersive X-ray fluorescence (EDXRF) analysis was used to determine the elemental composition of the aluminium foil and FTIR analysis was used to ascertain the composite formation between the foil and PVA. The blends have shown an impressive swelling property in aqueous system and poor to moderate in other organic solvents.
