An infrared study of adsorbed metal ions on modified silica: Comparative chelation between mercury, cadmium, and lead divalent ions to silica functionalized with ortho- and para-aminothiophenoles

► Binding effectiveness of 2-, 4-ASP-silica is explored by interacting with aq- solutions of Hg, Cd and Pb ions. ► Attaching 2-, 4-ASP to silica altered their binding for Hg, Cd and Pb ions. ► 4-ASP-silica preferentially binds HgII over Cd and Pb ions upon individual and simultaneous interaction. ►...
