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

In this work, Cs+ ion sorption on some clays and zeolite were investigated. Cs-137 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.
