Description

Zeolitic material prepared by hydrothermal treatment of brown coal fly ash was used for sorption separation of Co2+ and Zn2+ ions from single and binary solutions. Adsorption in single systems was rapid, pH dependent and follow the Langmuir isotherm. 3D sorption surfaces revealed competitive effects and mutual interactions between Co2+ and Zn2+ and significant preference for Zn2+ in binary system was confirmed. Surface retention and ion-exchange were most probably the principal mechanisms of Co2+ and Zn2+ removal. Zeolitic material with markedly high sorption capacity for Co2+ and Zn2+ can be a promising sorbent for removal of toxic metals and radionuclides. (author)
