Removal of uranium, cadmium and iron ions from phosphoric acid solution using amberjet 1200 H resin: an experimental, isotherm and kinetic study

Enhanced uranium extraction from seawater: from the viewpoint of kinetics and thermodynamics

“…These models encompass Weber and Morris sorption kinetic models, pseudo-first-order models, and pseudo-second-order models. 22,[35][36][37][38][39][40] Most studies on the thermodynamics of uranium adsorption indicate that the process is endothermic and spontaneous. 41,42 The nature and feasibility of the adsorption process are evaluated by calculating the Gibbs free energy, standard enthalpy, and entropy change.…”

Magnetic amino-sulfonic dual sorbent for uranyl sorption from aqueous solutions – Influence of light irradiation on sorption properties

“…Many types of sorbents have been tested for metal sorption (including U (VI) recovery) such as mineral sorbents [2,3], carbon-based sorbents [4], porous metal-organic framework [5,6], resins [7][8][9][10][11], and materials of biological origin [12][13][14][15][16].…”

“…The strong affinity of uranium for sulfonate groups [17][18][19] was a strong incentive for designing new resins bearing strong cation exchange functionalities [8,10,11,[20][21][22][23]. Sulfonation of composite was also used for designing sorbents for the recovery of rare earth elements: for example, algal biomass/polyethylenemine beads were functionalized by sulfonation for recovering scandium, cerium and holmium [24].…”
