... and characterized by high-resolution Ar adsorption volumetry. The overall results show that (1) HA interacts strongly with the basal surfaces of the clay, (2) Ca serves to establish Ca 2+ bridges between HA and clay, and (3) HA and clay interact via at least two distinct adsorption mechanisms. Two stock...
