The continuous extra-framework cations release from Greek analcime-rich rock sample was studied, upon ammonium acetate exchange experiments (agitation time 0.25-720 hours), using atomic absorption spectrometry. The analcime-rich material was examined by X-ray powder diffraction, scanning electron microscopy equipped with energy dispersive microanalytical system and atomic absorption spectrometry. Its sorption ability was measured using the Ammonium Acetate Saturation method. The monovalent cations K+ and Na+ after 720 hours, show only 7 and 10% of exchange, respectively. No steady state achieved for Na+. The bivalent cations Ca2+ and Mg2+ show better exchange, 97% for Ca2+ and 62% for Mg2+. The calculated rate of ion-exchange was 0.01 ppm/h for K+ and Mg2+, while 0.13 ppm/h for Na+ and Ca2+. The recorded behaviour on the multi-component ion-exchange system and the linear release of Na+ over NH4+ observed at a slow rate of ion-exchange, can allow us to propose studied analcime-rich rock as a potential material for waste-water purification and pet litter.
