Abstract:
In this study, strontium extraction with different resins from sulfuric acid solutions has been investigated. The extraction of strontium from aqueous solution can be achieved by adding a dowex50w cation exchange resin to the aqueous solution. Dowex50W-X8 with 200 - 400 mesh extracted 93.89% of Strontium from sulfuric acid solutions, at the ambient temperature. The effect of pH, temperature, mass of resin and concentration of interfering ions to optimize the conditions of using Dowex50W-X8 for removing strontium from aqueous solutions has been evaluated. The kinetics models of the sorption were analyzed using pseudo-first order and pseudo-second order kinetic models. The data showed that the pseudo-second order kinetic model was more appropriate for this system. Stripping experiments were also conducted with different stripping reagents independently.
