Synthesis and application of magnetic graphene/iron oxides composite for the removal of U(VI) from aqueous solutions

Immobilization and recovery of uranium(VI) using Na-bentonite from aqueous medium: equilibrium, kinetics and thermodynamics studies

“…3 that the distribution parameter (K d ) of U(VI) on the surfaces of Na-bentonite decreases gradually with the increasing of solid/liquid ratio. At low adsorbent concentration, all sorts of surface sites are totally exposed for sorption process and the material surface rapidly achieves saturation, thus bringing about a higher sorption capacity [27]. Nevertheless, the availability of higher energy sorption sites reduces with a fraction of lower energy sites being occupied, leading to lower sorption capacity at higher adsorbent concentration [28,32].…”

A biotechnological perspective on the application of iron oxide nanoparticles

“…Superparamagnetic Fe 3 O 4 NPs are the most frequently utilized iron oxides because they have low toxicity and good biocompatibility [105]. The bare iron MNPs often have high reactivity and easily undergo degradation upon direct exposure to certain environments, leading to poor stability and dispersity [106,107]. Various modification methods have been developed to obtain soluble and biocompatible iron MNPs for protein immobilization [21].…”

Three novel triazine-based materials with different O/S/N set of donor atoms: One-step preparation and comparison of their capability in selective separation of uranium

“…Potentiometric titration provides a measure of the sequential binding of the proton by the surface functional groups of carbonaceous materials [60]. Herein, CCTS, CCTU and CCU were characterized by potentiometric titration using NaOH (aq) as the titrant.…”
