Abstract
In this study, cesium adsorption performance of raw vermiculite
obtained from Sivas-Yıldızeli region of Turkey was investigated using batch
adsorption method. In order to obtain the optimum adsorption conditons; different
adsorbent dosages, contact times, solution pH’s, initial cesium concentrations
and temperature ranges were investigated. Amount of cesium ions and percentage
of cesium adsorbed by vermiculite in solution media were calculated using
ICP-OES technique and noted as mg/g and %adsorbed Cs. Kinetic studies demonstrated
that adsorption process was in accordance with second order pseudo kinetic
model and equilibrium isotherm modeling studies showed that the process was
compatible with Langmuir, Freundlich and Temkin adsorption isotherm models
meaning the Cs adsorption process had both phsyical and chemical character. Negative
Gibbs energy values obtained from thermodynamic studies revealed that the
adsorption process was spontaneous and had a high feasibility. Additionally, negative
enthalpy value indicated that process was exothermic, meaning the amount of Cs
ions decresead with increasing reaction temperatures and positive entrophy
value showed that disorderliness between solid-liquid phase increased during
adsorption. Results clearly indicate that vermiculite mineral has a promising
potential in removing Cs+ ions from aqueous media which leads
mineral may also be used in decomposing and efficiently removing radioactive
cesium from contaminated waters.
