“…Chattopadhyay et al have extensively studied in the field of synthesis of nano and microstructures inorganic ion exchangers (and composites) and their application for adsorption and separation of metal ions particularly in the radio active media due to the excellent stability of these materials toward thermal and radiation dose [5]. They have synthesized different inorganic ion exchanger such as Sodium titaniumsilicate for separation of 90 Y from 90 Sr [6], aluminum vanadate for for separationof 137m Ba,115m In and 110m Ag from 137 Cs, 115 Cd and 198 Au [7], cerium(IV) iodotungstate for separation of the 90 Sr-90 Y pair and nanostructured zirconium phosphate for seperation of 137m Ba from 137 Cs [8]. They have investigated the size-dependent ion exchange property of the inorganic ion exchcangers and composites thoroughly [9].…”

A new FeIII x SnII y SnIV 1-x-y H n [P(Mo 3 O 10 ) 4 ]Á xH 2 O nano-hybrid was synthesized by chemical co-precipitation. The product was characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) spectroscopy. From TEM images, the size of the product was estimated to be smaller than 30 nm. The adsorption efficiency of the obtained hybrids were determined for Sr(II) and Th(IV) ions. The kinetics and thermodynamic of metal ions were studied. Results explained that the pseudo second-order sorption mechanism is predominant and the sorption of each ion is an endothermic process.

“…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 ].…”

There is growing demand for separation of 90Y carrier free from 90Sr coexisting to produce high purity 90Y essential for radiopharmaceutical uses. Thus, in this context the sorption profiles of Y3+ and Sr2+ from aqueous solutions containing diethylenetriaminepenta acetic acid (DTPA), ethylenediaminetetra-acetic acid (EDTA), acetic acid, citric acid, or NaCl onto Chelex-100 (anion ion exchange) solid sorbent were critically studied for developing an efficient and low-cost methodology for selective separation of Y3+ from Sr2+ ions (1.0 × 10−5 M). Batch experiments displayed relative chemical extraction percentage (98 ± 5.4%) of Y3+ from aqueous acetic acid solution onto Chelex-100 (anion ion exchanger), whereas Sr2+ species showed no sorption. Hence, a selective separation of Y3+ from its parent 90Sr2+ has been established based upon percolation of the aqueous solution of Y3+ and Sr2+ ions containing acetic acid at pH 1-2 through Chelex-100 sorbent packed column at a 2 mL min−1 flow rate. Y3+ species were retained quantitatively while Sr2+ ions were not sorbed and passed through the sorbent packed column without extraction. The sorbed Y3+ species were then recovered from the sorbent packed column with HNO3 (1.0 M) at a 1.0 mL min−1 flow rate. A dual extraction mechanism comprising absorption associated to “weak-base anion exchanger” and “solvent extraction” of Y3+ as (YCl6)3− and an extra part for “surface adsorption” of Y3+ by the sorbent is proposed. The established method was validated by measuring the radiochemical (99.2 ± 2 1%), radionuclide purity and retardation factor (Rf = 10.0 ± 0.1 cm) of 90Y3+ recovered in the eluate. Ultimately, the sorbent packed column also presented high stability for reusing 2-3 cycles without drop in its efficiency (±5%) towards Y3+ uptake and relative chemical recovery. A proposed flow sheet describing the analytical procedures for the separation of 90Y3+ from 90Sr2+ using chelating Chelex 100 (anion exchange) packed column is also included.

This research is dedicated to the study of analytical application of poly[dibenzo-18-crown-6] for separation of Nd(III) from possible lanthanides, actinides and other metal ions. A simple and efficient column chromatographic method has been developed using poly [dibenzo-18-crown-6] as stationary phase and hippuric acid as a counter ion. The capacity of crown polymer for Nd(III) was found to be 0.55 ± 0.01 mmol/g. Nd(III) was quantitatively separated from Ce(III), U(VI) and other elements in binary as well as multicomponent mixtures. Separation yields were good and reproducible (±2 %). This method has important application for separation of Nd(III) from Ce(III) rapidly and selectively.
