Title

REMOVAL OF STRONTIUM IONS BY SYNTHETIC NANO SODALITE ZEOLITE FROM AQUEOUS SOLUTION

Pages

  160-169

Abstract

 In this article, a novel nano SODALITE ZEOLITE was synthesized and characterized by X-ray diffraction, scanning electronic microscopy (SEM) and infrared spectroscopy and evaluated in order to facilitate the sorption of STRONTIUM ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The optimum conditions of sorption were found as follows: a sorbent amount of 0.25 g in 100 mL of STRONTIUM solution (50 mg/L), contact time, pH and temperature of 80 min, 6 and 20oC, respectively. To study the KINETICs of removal process, three equations, i.e. Morris–Weber, Lagergren (pseudo first order) and pseudo second order were used. The STRONTIUM sorption process was well described by the pseudo second order (type 2) KINETIC model. The Langmuir, Freundlich, Dubnin-Randkovich (D-R) and Temkin models were subjected to sorption data to estimate sorption capacity, intensity and energy. An evaluation of the THERMODYNAMIC parameters including ΔH, ΔS and ΔG was done. It was found out from THERMODYNAMIC parameters that the sorption of STRONTIUM onto zeolite was feasible, spontaneous and endothermic under studied conditions.
