Kinetics and equilibrium sorption models: Fitting plutonium, strontium, uranium, and neptunium loading on monosodium titanate (MST)
The Dubinin-Astashov (DA) isotherm parameters for U, Pu, Sr, and Np have been updated to include additional data obtained since the original derivation. The DA isotherms were modified to include a kinetic function derived by Rahn to describe sorbate loading from the beginning of sorption up to steady state. The final functions describe both kinetic and thermodynamic sorption.
