[Display omitted] •Aluminum-based water treatment residuals can irreversibly adsorb PFOA and PFOS.•PFOS adsorption on the residuals was greater than PFOA adsorption.•PFOA and PFOS adsorption was pH-dependent; adsorption was higher at lower pH.•Repurposing an industrial waste is a sustainable option...
