Abstract

In this study, a simple and novel photocatalytic tool was proposed and developed for photoelimination of toxic metal ions in aqueous solution. CdS quantum dots capped with thioglycolic acid and CdS @ magnetized powder activated carbon (CdS@MPAC) fixed on magnetic stir bar was constructed and applied for photoelimination of toxic metal ions in aqueous solutions. The production and contribution of hydroxyl (OH•) and superoxide (O2•−) species generated during photoelimination process were investigated. The photoelimination of Cd(II), Co(II), Cu(II), Mn(II), Ni(II) and Pb(II) metal ions was performed at neutral pH (7.0± 0.1) with the same experimental circumstances.Maximumremoval efficiency was achievedwith 0.360Mof CdS@MPAC under 3.0 h daylight irradiation. Photoeliminationmechanisms of Cu2+with CdS QDswere also investigated. Finally, thismethod was successfully applied for elimination of toxic metal ions from real sample
