Kinetic and thermodynamic studies on the interaction of europium(III) and phosphate with γ-Al2O3
摘要：
The temperature effect on the co-sequestration process receives little attention. Herein, kinetic and thermodynamic studies on the co-sequestration of Eu(III) and phosphate by γ-Al2O3 were investigated by batch experiments. The standard thermodynamic parameters (H0, S0, and G0), the activation thermodynamic parameters (H, S, and G), and the activation energy (EA) for the co-sequestration process were obtained. Based on EA and S values, Eu(III) and phosphate co-sequestration is controlled by chemical reactions on γ-Al2O3 and by an associative mechanism. This work highlights the temperature effect on the co-sequestration of Eu(III) and phosphate in a geological environment.
