“…To increase the efficiency of separation, it is desirable to develop effective separation resins for Pu(IV), as well as other resins for metal ions. [8][9][10][11][12] Microbial metabolite desferrioxamine B (DFB), a trihydroxamate-based siderophore produced by the actinobacteria Streptomyces pilosus, has a very strong chelating ability for many high-valence ions under certain conditions. [13][14][15] For instance, it has been reported that DFB chelates with Pu(IV), 13,14 Am(III), 16 Cm(III), 17 and U(VI) 15 in aqueous solution.…”

The adsorption properties of Pu(IV), Am(III), Cm(III), and U(VI) on desferrioxamine B-immobilized micropolymeric resin (DMPs) and adsorbed species were elucidated using thermodynamic constants and log β values. This allowed the determination of adsorption characteristics (91, 95, 88, and 97% for Pu(IV), Am(III), Cm(III), and U(VI), respectively) and individual pH-independent adsorption properties. Pu(IV) could be separated from Am(III), Cm(III), and U(VI) at pH 2. The separation of Pu(IV) from Am(III), Cm(III), and U(VI) was achieved by controlling the pH of the solution using a single resin.

“…Solid-phase extraction using a chelating resin is one of the useful techniques for separation and preconcentration of trace elements. [1][2][3][4] Chelating resins immobilizing various functional groups can be purchased from suppliers; 4 among them, a chelating resin immobilizing aminocarboxylic acid is widely used because it can extract many elements. 5 New generation of the chelating resins immobilizing aminocarboxylic For the carboxymethylation of amino group in PAA on the resin, 1 g of the resin immobilizing PAA was taken, and then 10 mL of 1 mol L -1 sodium hydroxide solution containing various amounts of MCA were added; the amounts are appended in Table 1.…”

New chelating resins immobilizing carboxymethylated polyallylamine (CM-PAA) were prepared by immobilizing PAAs with some molecular weights on methacrylate resins and then carboxymethylating a part of amino groups in the PAAs using various amounts of sodium monochloroacetate. The molecular weight of PAA barely affected both the amount of PAA immobilized on the resin and the relationship between the carboxymethylation (CM) rate and the ratio of the amount of monochloroacetate used in the CM step. The selectivity of CM-PAA resin for solid-phase extraction of trace elements was almost the same as that of a resin immobilizing carboxylymethylated polyethyleneimine; 10 elements, namely Cd, Co, Cu, Fe, Mo, Ni, Pb, Ti, V, and Zn, could be quantitatively recovered over a wide pH range and alkali and alkaline earth elements were scarcely extracted under acidic and neutral conditions. The CM-PAA resin was applicable to the separation and preconcentration of the elements in a certified reference material (Waste Water, EU-L-1) and a real environmental water sample (ground water).

These resins scarcely extract alkali and alkaline earth elements, which are sometimes contained at high concentration in various environmental samples and are often interfered with the determination of trace elements using atomic spectroscopy, under acidic and neutral conditions. 5,20 The selectivity of such chelating resins has been studied using chelating resins immobilizing Analytical Sciences
