The presence of small nanopores in minerals was recently shown to strongly impact the adsorption of cations, also known as the nanopore inner-sphere enhancement (NISE) effect. The role of various Si/Al ratios in different zeolites on the NISE effect was investigated. This study presents pH-dependent data on the adsorption of sodium (Na+), potassium (K+) and cesium (Cs+) on ZSM-5 zeolite. The competitive role between each element was also quantified using high performance liquid chromatography (HPLC). The adsorption data show a correlation of hydration energy with adsorption strength.
