Abstract
In this study, the investigation of Se(IV) adsorption on modified Reşadiye bentonite with aluminium-polioxy cations was investigated. In adsorption experiments, 75Se that was produced by neutron activation in İTÜ TRIGA MARK II nuclear research reactor and has similar chemical properties but shorter half-life with 79Se. Adsorption experiments on modified bentonite were implemented by using batch technique for various time and solid-liquid ratios by using measurements with high resolution gamma spectrometry system. The characterization with XRD, FTIR, and TGA-DTG methods confirmed that aluminium-polioxy cations interchalated to the interlayers and the bentonite structure was not affected. The basal spacing of the modified bentonite and the zeta potential is obtained as 1.853 nm 45.3±6.1 mV, respetively. Due to the realized structural changes, inorganic modification improves the adsorption ability of Reşadiye sodium bentonite from 2% to 100%. Evaluation of adsorption results showed that adsorption mechanism follows the pseudo second order reaction kinetic.
