“…It Brought to you by | New York University Bobst Library Technical Services Authenticated Download Date | 5/30/15 1:15 PM was found that the uptake percentages attained after equilibrium are 82% and 61% for adsorption onto iron ferrite and natural magnetite, respectively. Kulyukhin et al [11] investigated the sorption of 131 I, 137 Cs, 85 Sr and F − ions on synthesized alkaline earth (AE) (calcium, strontium and barium) hydroxyphosphate. The results obtained showed that the degree of 137 Cs and 85 Sr sorption recovery from aqueous solutions upon their 120 min contact with AE hydroxyphosphate is ∼ 5-25% and ∼ 15-80%, respectively.…”

Liquid radioactive / Waste treatment / Ion exchange / Radionuclides / Complexant / Cesium removalSummary. Various types of liquid radioactive wastes are released from different nuclear activities. The treatment efficiencies of these wastes depend highly on the physical and chemical composition of each waste such as pH, TDS and electrical conductivity. The treatment efficiency of some radionuclides with different valency states (such as 134 Cs, 65 Zn, 60 Co and 152+154 Eu) was tested based on the absorption capacity of cationic exchanger (KY-2) functionlized with polystyrene sulphonic group. The competitive adsorption on cationic exchanger was investigated by mono radionuclide and multi radionuclides wastes. The influence of the presence of various anionic complexants in the rad-waste on the adsorption capacity and hence the treatment efficiency was quantitatively studied using weakly base aminated anionic exchanger (AN-31). The enhancement in decontamination factor of each radionuclide is mostly attributed to the high adsorption capacity of the cationic resin in addition to the complexation capability of the radionuclide with the different complexant existed in the waste solution. The complex formation improved the decontamination factor through indirect adsorption of the anionic species on the subsequent anionic exchanger during the treatment process. The results showed that the removal percentages are around 50% for 134 Cs, 60 Co, 65 Zn and 152,154 Eu, without complexant compound. Significant enhancements of the removal percentages > 85% were obtained for 60 Co, 65 Zn and 152,154 Eu, respectively, on addition of manganese sulphate while maximum removal percentage (75.3 ± 0.7%) is obtained for 134 Cs when using 0.1 M citric acid as a complexing agent.

“…A study has been made of the adsorption of americium onto a-alumina 220 and of [ 99 Mo]molybate anions onto hydrated aluminas. 221 Similarly it has been found that uranyl cations are adsorbed by hydroxyapatite, 222 that iodine, caesium and strontium radionudlides are adsorbed onto hydroxyphosphates 223 and that rare earth, neptunium and plutonium ions can be adsorped 224 onto calcite. Stronium-90 cations are adsorbed 225 onto the structurally similar magnesite and also onto kaolinite.…”

Following last year's precedent this section of Annual Reports will review not only recent progress in radiochemistry, including isotope production and environmental aspects, but also in the production of radiopharmaceuticals and their use in nuclear medicine for imaging. Radiation chemistry (unless related to the stability of labelled molecules), the use of nuclear activation analysis and the inorganic chemistry of elements that are by their nature, radioactive are all excluded. HighlightsThe IAEA published 1 the results of a wide ranging review of nuclear measurements. Conferences held during 2005 which covered progress in radiochemistry, included the '4th all Polish Conference on Radiochemistry and Nuclear Chemistry' 2 and the '7th Nuclear and Radiochemistry Symposium' 3 whilst a more focused meeting dealt with the production and application of labelled compounds 4 in the oil industry. A couple of very interesting articles appeared during 2005 questioning what exactly is meant by many fundamental 'radiochemical' concepts 5 such as 'specific activity' and 'carrier-free' and indeed how the specific activities 6 of 'no-carrier-added' materials can be determined. The Proceedings of the 16th Symposium on Radiopharmaceutical Chemistry 7 covers advances made in radiopharmaceutical development and applications while the Proceedings of the Society of Nuclear Medicine 8 and the European Society of Nuclear Medicine 9 cover both radiopharmaceutical development and the application in diagnosis and therapy. A critical review has been published 10 on the application of positron emitting nuclides for use as radiopharmaceuticals.

“…Sylvester's measurements on Nanonatitanate yielded a K d of 3.2 × 10 4 mL/g, and Na-titanate yielded a K d of 5.8 × 10 4 mL/g (Marinin and Brown 2000). Many calcium-based minerals were tested, but most produced very low K d values (Vojtěch et al 1974;Song et al 2013;Ivanets et al 2014;Kulyukhin et al 2005). Only Ca-alginate beads in a solution without competing cations produced a maximum K d of 1.6 × 10 3 mL/g (Song et al 2013).…”

A system for rapid reduction of radioactive contamination and recycle of contaminated waters is called the Integrated Wash-Aid, Treatment, and Emergency Reuse System (IWATERS). First developed for cesium contaminations, IWATERS prescribes the use of salt and surfactant additives to decontaminate radionuclides from urban surfaces. The water is collected and recycled after passing through reactive filtration beds containing selective sorbents. To adapt the IWATERS for strontium contaminations, potential additives to enhance its decontamination from urban surfaces are identified. One possible additive is calcium (Ca 2+ ). However, its concentration can have a very strong detrimental effect on the ability of selective sorbents to remove strontium from spent wash water. We recognized that studies on off-the-shelf sorbents that include Ca 2+ concentrations at relevant levels (greater than millimolar) are absent in the literature. To understand better the effect of Ca 2+ , we completed a literature review, batch tests, and surface complexation modeling to reveal few sorbent options. Only silico-titanate sorbents exhibited high K d values in the presence of Ca 2+ , but have significant drawbacks in cost and availability. Given the state of the art, it is imperative that alternatives to alkaline earth ions in the IWATERS be identified to permit in situ recycle of the wash waters.
