Cellulose/silsesquioxane grafted Ti3C2Tx MXene for synergistically enhanced adsorption of uranium

Efficient Separation of Uranium(VI) by CaCO3-Doped Chitosan with PO43– Modification: Adsorption Behaviors and Mechanism Study

“…Obviously, the correlation coefficient (R 2 ) of the pseudosecond-order kinetic model was higher than the other kinetic model and the calculation value of q e from the pseudo-secondorder kinetic model was closer to the experimental data, which indicated that the pseudo-second-order kinetic model could more accurately describe the adsorption behavior of CaCO 3 @ aCS/PA for uranium, namely, uranium species were captured using CaCO 3 @aCS/PA from solution by the chemical process. 47,48 Furthermore, the pseudo-second-order kinetic model was used to calculate the adsorption rate of CaCO 3 @ aCS/PA for uranium at different adsorption times. As depicted in Figure 3b, the adsorption rate weakened significantly with the increase in the adsorption time, which was caused by the considerable drop in the uranium concentration in solution.…”
