In this study, acid-doped polyaniline-zinc oxide composites were prepared and used to investigate their effect on the removal of methyl orange dye under visible light exposure. The composites were prepared by mixing different volume fractions of polyaniline and ZnO powders. Their effect on the removal of methyl orange was determined through transmittance spectroscopy. Polyaniline-zinc oxide composites of 75% volume fractions showed the highest percent removal of methyl orange. This was attributed to the presence of p-n heterojunctions and adsorption capability of the polyaniline molecules.
