Distribution of 14 elements from two solutions simulating Hanford HLW Tank 102-SY (acid-dissolved sludge and acidified supernate) on four cation exchange resins and five anion exchange resins having different functional groups

Biosorption of uranium(VI) from aqueous solution using calcium alginate beads

“…Synthetic polymers such as ion-exchange and chelating resins have been widely used as effective adsorbents to collect radionuclides, toxic metals, precious metals and base metals from aqueous solutions [5][6][7]. Recently, naturally occurring biopolymers have been known to exhibit excellent adsorption ability for multivalent metal ions [8,9].…”

Alpha Spectrometric Determination of Trace Level of 239-240Pu and 238Pu Uranium Compounds and Solutions

“…Among the anion-exchange resins available commercially, REILLEX™ HPQ has been chosen because of its macroporous nature which permits high flow rates through the columns, especially for Pu elution. This resin has been often used for plutonium Separation [30][31][32][33] and some studies have shown its great resistance to radiolysis and nitric acid oxidation [30,31]. Table 2 presents U(VI) and Pu(rV) distribution coefficients Ko (in mL • g-') between REILLEX™ HPQ resin in nitrate form and 4 M and 7 M HNO3 aqueous solutions.…”

Catalytic behavior of Mn during molten salt oxidation of cationic exchange resins in Li2CO3–Na2CO3–K2CO3 melt

“…Nuclear wastewater has a variety of long decay cycle nuclide ions, which are toxic, cannot easily degrade naturally, and need to be purified using ion exchangers. 2 Cation exchange resins are frequently used to remove nuclides ( 60 Co, 137 Cs, 85 Sr, 54 Mn, etc. ) from wastewater owing to the advantages of its nuclear-grade purification capacity and low operating costs.…”
