Abstract
The composite was used for sorption of strontium from solution. It was found that the kinetic of strontium sorption by the composite could be modeled by pseudo-second order. Among the isotherms applied to modeling the sorption in various concentrations, the Langmuir isotherm was founded to be more appropriate to fitting the experimental data. An excellent correlation coefficient was obtained (R2â¯>â¯0.98). The qmax for sorption of strontium ions which was calculated by Langmuir model was 80â¯mg/g. The thermodynamic parameters were calculated by determination of sorption in various temperatures and using the Vant Hoff plot. ÎG°, ÎHâ¦, and ÎS⦠were calculated as â19.15, 2.28 and 0.071â¯kJ/mol respectively.
