  "description" : "1,3-[(2,4-Diethylheptylethoxy)oxy]-2,4-crown-6-Calix[4]arene(Calix[4] arene-R14), used as an extractant of Cs(I) from nitric acid, modified by dodecanol and dodecyl benzenesulfonic acid (DBS), was loaded into the pores of macroporous silica-based polymer support (SiO{sub 2}-P) particles. To evaluate the stability of the adsorbent, the adsorption data at different temperatures (298–323 K) and γ-ray absorbed doses (10–200 kGy) were analyzed by the Langmuir isotherm. The minimum adsorbed amount was calculated to be 0.121 mmol g{sup −1} at 323 K, approximately 23% reduction compared to 298 K. The maximum adsorbed amount of not-irradiated adsorbent with 0.156 mmol g{sup −1} decreased by 20% than that irradiated in 0.5 M HNO{sub 3}. The thermodynamic parameters have revealed that this adsorption reaction is an exothermic and spontaneous process. The reduction in 3 M HNO{sub 3} was about 45% by the comparison between the before- and after-irradiation. It was found that both the concentrations of HNO{sub 3} and DBS have significant influence on the degradation of the adsorbents. - Highlights: • The adsorbed amount of Cs(I) on the adsorbent decreases with increasing temperature. • The values of G° and H° are calculated from the plots of ln K{sub L} versus 1/T. • The adsorption ability of the irradiated adsorbent for Cs(I) decreases with increasing dose.",
