Synthesis of phillipsite from perlite utilizing mother waters from wet gel EMT preparation and study of the obtained zeolitic material as ion exchanger

摘要

In the present paper, a supplementary method was elaborated for synthesis of phillipsite from perlite utilizing mother waters from wet gel EMT preparation. The method is reproducible and cheap-synthesis was performed at mild conditions at 90 degrees C. One of the obtained phillipsite samples was tested as ion exchanger with solutions containing K+, Cs+ and Sr2+ for simulated radioactive fixation of these ions. The kinetics of ion exchange was adequately described by pseudo-second-order kinetic model equations. The obtained parameters for the ion exchange properties of the synthesized phillipsite show that this material could be used in the Cs+ and Sr2+ removal in decontamination processes. Cation-exchange effectiveness was also tested for Cs+ and Sr2+ solutions, contaminated with model nonionic surfactant Pluronic 123, which may appear as a municiple pollutant.
