Synthesis and Evaluation of Reusable Desferrioxamine B Immobilized on Polymeric Spherical Microparticles for Uranium Recovery

Abstract

Development of techniques for the separation and removal of uranium from wastewater and other sources is an active area of research because of the increasing demand for uranium for nuclear energy generation. However, reusable adsorption materials with specific sizes and uniform shapes that can exhibit high affinity for uranium are still scarce. In this work, we describe the modification of an acrylic micropolymer resin with desferrioxamine B and the evaluation of its adsorption property for uranium(VI). The obtained microparticles with specific sizes exhibit a uniform spherical shape, thus enabling the design of either batch or continuous flow column adsorption systems with good adsorption ability for U(VI) and can endure highpressure conditions [at least 100 kgf/cm 2 (equal to 9.8 MPa)]. The mechanism of adsorption is investigated using chemical kinetics and thermodynamics. Selectivity experiments reveal that the present system adsorbs U selectively in the presence of high competitive ion concentrations. Furthermore, the reusability of the resin after 10 adsorption−desorption cycles is demonstrated.

Adsorption Behavior of Pu(IV), Am(III), Cm(III), and U(VI) on Desferrioxamine B-immobilized Micropolymer and Its Applications in the Separation of Pu(IV)

“…The adsorption behavior of U(VI) with DMPs has already been reported by the authors, 18 although the experimental conditions are different from those of the previous report. The adsorption mechanism of U(VI) on DMPs has also been discussed in the literature.…”

“…Although DFB-immobilized micropolymeric adsorbents (DMPs) (Fig. 1) have been developed, 18 the adsorption properties of actinide ions except U have not been elucidated.…”

A pilot study on the effect of desferrioxamine B on uranium VI precipitation and dissolution in pH 11.5, 0.1 M NaCl solutions

“…To the best of our knowledge, there is a limited number of studies that have investigated U VI interactions with DFOB above pH 10, the region where U precipitation happens. For example, a recent study grafted DFOB onto microparticles and investigated the ability of the DFOB-modified microparticles to extract U VI from wastewater through batch and column experiments [27]. The pH of the batch experiments varied between pH 2 to 12 and peak absorption of U VI was observed at ca.…”

Kinetic and thermodynamic sorption studies of Fe(iii) and Zr(iv) by DFO@Purolite, a desferrioxamine B based chelating resin

“…11–23 The successful implementation of DFO in practical analytical devices rests on its high affinity for hard Lewis acid cations, on the appearance of rather intense charge-transfer absorption bands in the visible range upon complex formation with ions like Fe 3+ or UO 2 2+ , 24 but also on the ease to immobilize the chelator on a surface or to incorporate it into a solid matrix. 25,26 Thanks to the terminal primary amino group of DFO, several strategies have been proposed to functionalize different solid supports, such as nylon, 27 cellulose, 11,18,28 sepharose, 29 acrylate polymers, 30,31 or silica-based materials. 12,13,16,17,20,32…”
