Ion-Specific Effects of Alkaline Earth Metal Ion Binding to an Anionic Carboxylate Monolayer.

ABSTRACT: The ion-specific effects of alkaline earth metal ions binding to anionic carboxylate-terminated monolayers influence environmental chemistry, industrial processes, and nanotechnology. Experimental results obtained using interfacial techniques are often interpreted by using data from dilute aqueous solutions of carboxylate anions. However, atomic force microscopy (AFM) adhesion forces reported for alkaline earth metal ions binding at the aqueous interface of an anionic carboxylate-terminated monolayer contradict data reported for dilute solutions of aqueous carboxylate anions. To reconcile this data and provide molecular insight into the ion-specific trends observed in the AFM data, classical atomistic molecular dynamics (MD) simulations are used to model Mg²⁺, Ca²⁺, S
