As a typical dioctahedral clay mineral with large

The MMT@C has the highest sorption at T = 333 K and the lowest sorption at T = 298 K, which demonstrated frontal lobe U(VI) sorption was promoted by temperature. The thermodynamic parameters (ΔH0, ΔS0 and ΔG0) were calculated from the following equations:equation(7)ΔG0=RT ln(K0)ΔG0=RT ln(K0)equation(8)ln(K0)=ΔS0R−ΔH0RTwhere R is the universal gas constant (8.314 J mol−1 K−1), T is the temperature in Kelvin and K0 is the equilibrium constant of sorption reaction (i.e.
