The retention of monovalent and divalent cations increases in constrained environments. It is particularly important to note that in medium-sized pores (~0.5 nm) the retention of monovalent ions greatly exceeds the retention of divalent ions. This phenomenon is explained by the Nanopore Inner-Sphere Enhancement (NISE) Theory. An explanation of the NISE theory is presented along with proof of the theory based on data from flow calorimetry and electron paramagnetic resonance (EPR) spectroscopy.
