Retention profile and selective separation of 90Y from 89Sr using zirconium-vanadate gel packed column

Retention profile and chromatographic separation of Y3+ from Sr2+ by Chelex-100 (cation ion exchanger) physically immobilized with ammonium ion

“…Hence, water structure enforced ion-pairing is the driving force of Y 3? retention [34]. The ion-associative interaction of the available active sites of the sorbent with Y 3?…”

“…Such ion exchangers are suitable and economically viable for the separation in column chromatography. Based on this basis and in continuous to our work [34,35], great attempts have been made to separate carrier-free 90 Y from its parent 90 Sr with the modified Chelex-1000 solid phase extractor. Thus, the present article is focused on: (i) studying the retention profile of Y 3?…”

“…A series of inorganic ion exchangers such as clinoptilolite [27], sodium titanosilicate, sodium nonatitanate [28], cerium (IV) iodotungstate, zirconium oxide in multiple steps [29], stannic molybdophosphate immobilized on multiwalled carbon nanotubes [30], sodium titaniumsilicate [31], quinolinephosphomolybdate [32], zirconium vanadate [33], and zirconium-vanadate gel ion-exchanger [34,35] have been used for separation of 90 Y from its parent 90 Sr. Such ion exchangers are suitable and economically viable for the separation in column chromatography.…”

Sorption Characteristics and Chromatographic Separation of 90Y3+ from 90Sr2+ from Aqueous Media by Chelex-100 (Anion Ion Exchange) Packed Column

“…With this background in mind, taking into account the importance of highly pure 90 Y 3+ , the characteristics of the chelating group iminodiacetate moieties of the Chelex-100 anion ion exchanger and some of the synthesized inorganic sorbents as ideal and ecofriendly solid sorbents and in continuation to our previous study [ 10 , 38 – 43 ], the current study is aimed to (i) revising the sorption profiles of Y 3+ and Sr 2+ onto the anion ion exchanger as a new candidate solid sorbent, (ii) establishing a simple and low cost and selective chromatographic separation of 90 Y from its parent 90 Sr by chelating Chelex-100 (anion ion exchanger) sorbent packed column and finally, and (iii) testing the reusability of the established chelating Chelex-100 sorbent packed column towards separation of Y 3+ from its parent Sr 2+ species in aqueous solutions. These results are supportive to recognize the analytical utility of the Chelex-100 in nuclear medicine, waste management and to properly assign the physicochemical behavior of radionuclide 90 Y 3+ and 90 Sr 2+ .…”

“…However, some of these methods have many drawbacks and limitations such as complexity, high cost, the necessity for suitable operation, and preconcentration due to their low capacity. Therefore, searching for establishing low cost, simple systems with short analytical time and ruggedness for chromatographic separation of Y 3+ from Sr 2+ species in aqueous solutions with good radiochemical and radionuclide purity are much sought after [ 37 , 38 ].…”
