dc.description.abstract | To efficiently remove cesiuni ions from aqueous solution, sericite was used as a novel adsorbent. The silanol (SiO2) and aluminol (Al2O3) groups in sericite are likely to play an important role in adsorption process. The maximum adsorption capacity (q(m)) and adsorption constant (K-L) for cesium ions obtained from the Langmuir isotherm model were 6.68 mg/g and 0.227 L/mg, respectively and regression curve fit well with the experimental data as the 0.965 of correlation coefficients (r(2)). However, when the Freundlich isotherm model was used correlation coefficient (r(2)) was 0.973. Therefore, it was concluded that Freundlich model fits equilibrium data better than Langmuir model. When the 6.0 g/L of sericie concentration was added to aqueous solution, cesium ions were removed by about 80% and the increase was not happened above 6.0 g/L of sericite concentration any more. The process was determined as exothermic reaction because the removal efficiency of cesium ions decreased as temperature increased. Furthermore, all adsorption was completed in 120 min and comparing the pseudo first and second-order kinetic models indicates that the adsorption of cesium ions using sericite follows well the pseudo-second-order kinetics. | - |
