Description
For uranium adsorption in water, a new uranium adsorbent was synthesized by preparing poly(tetraethylenepentamine-trimesoyl chloride). The samples were characterized using SEM, EDS, TGA, FTIR and XPS. The removal ability and adsorption mechanism of uranium (VI) in an aqueous solution by poly(tetraethylenepentamine-trimesoyl chloride) were systematically studied. The results showed that the adsorption equilibrium was completed within 80 min, the adsorption capacity reached 189.82 mg g-1, and the removal rate reached 94.91%. The adsorption process fitted well with the pseudo-second-order model and the Langmuir isotherm model. The thermodynamic analysis indicated that the adsorption was an endothermic and spontaneous process. This study proved that poly(tetraethylenepentamine-trimesoyl chloride) could be considered a highly efficient and sustainable material for the removal of uranium (VI) from aqueous solutions. (author)
