Water Decontamination over Functionalized Defective Zr-MOFs: Investigation theCompetitive Roles of -NH۲ and -SH Sites in Removal of As(III) Species

Three novel functional Zr-MOFs, were fabricated to investigate the competitive or cooperative roles offree amine/thiol site in the removal of As(III). XPS and ATR revealed that amine sites in Gly@UiO-۶۶ have higheraffinity to As(III) (۳۰۱.۴ mg.g-۱) than thiol sites in Mer@UiO-۶۶ (۲۳۹.۸ mg.g-۱) and Cys@UiO-۶۶.
