The sorption behavior of Cs + ion on clay minerals and zeolite in radioactive waste management: Sorption kinetics and thermodynamics

摘要

In this work, Cs + ion sorption on some clays and zeolite were investigated. 137Cs was used as a tracer. Activities were measured with a NaI crystal gamma counter. The particle size distribution was determined by a laser sizer. Surface area of the particles were determined by BET (Brunauer, Emmett and Teller method). Structure analysis was made by using X-ray diffraction. The chemical compositions of the solid samples were determined using a ICAP-OE spectrometer. Kinetic and thermodynamic parameters were determined. Due to very high uptake results; clay and zeolite can be proposed as a good sorbents in waste management considerations. © 2011 Akadémiai Kiadó, Budapest, Hungary.
