“…[9] The PUREX process for plutonium/uranium separation, for example, is based on the extracting ability of tributylphosphate. [10] Efforts to improve the performance of a group of simple monofuntional organophosphorous extractants, such as the well-known trioctylphosphine oxide (TOPO, , using the former to mimic the trivalent actinides and the latter to mimic the tetravalent actinides present in liquid nuclear waste. The calixaryl phosphine oxides used for this purpose were 1 a ± f, as well as four other phosphine oxide calixarenes of group 1, with either dodecyl groups in para position instead of tert-butyl groups (n 4) or with n-butyl groups on the phosphorus instead of phenyl groups (n 4,6,8).…”

“…For example, the extracting ability of tributylphosphate forms the basis of the PUREX process for separating plutonium and uranium. [10] Bifunctional organophosphorus extractants include carbamoylphosphonates (CMPs) and carbamoylmethylphosphine oxides (CMPOs). [9] We have recently reported in a preliminary paper on the high efficiency in the extraction of Eu III , Th IV , Pu IV and Am III from inactive and simulated radioactive wastes of tetra-, hexaand octaphosphine oxides with or without tert-butyl groups at the para positions of the phenolic rings [6] (Scheme 1: compounds 1 a ± f).…”

Extraction and Complexation of Alkali, Alkaline Earth, and F-Element Cations by Calixaryl Phosphine Oxides

A series of new calixarene derivatives with phosphine oxide groups on the lower rim and, for comparison, a series of noncalixarene phosphine oxides have been synthesised. Their extraction power for alkali and alkaline earth cations from aqueous metal picrate solution into dichloromethane have been determined as well as the stability constants in methanol of the 1:1 complexes of several members of the calixarene series. Important selectivity trends are revealed by both methods. The extraction power from aqueous nitrate solutions (1m in HNO 3 ) towards europium(iii), as a model for trivalent actinides, and thorium(iv), as a model for tetravalent actinides, has been studied in detail for eight symmetrical calixarene derivatives, which differ in either calixarene size (4, 5, 6 or 8), the substituent at the upper rim (tert-butyl or hydrogen) or the number of methylene groups separating the phenolic oxygen atoms from the phosphorus atoms (1 or 2). The stoichiometry of the extracted species was characterised by a classical log ± log plot analysis. All the calixarenes tested are far better extractants than typical noncalixarene extractants, for example, TOPO and CMPO, currently in use in the treatment of radioactive waste; they extract thorium better than europium. The influence of the nitric acid concentration and of the sodium nitrate concentration in the aqueous phase on the extraction efficiency was also examined in order to assess the possible application of these compounds for the decategorisation of liquid nuclear waste. Several thorium complexes have been characterised by their stability constants in methanol.

Skeletal uptake of radiolabeled‐1, 4, 7, 10‐tetraazacyclododecane‐1, 4, 7, 10‐tetramethylene phosphoric acid (e.g., 177Lu‐DOTMP) complex, is used for bone pain palliation. The moderate energy of β‐emitting .15em177Lu false(normalT1/2=6.7 d,normalEβmax=497 keVfalse) has been considered as a potential radionuclide for development of the bone‐seeking radiopharmaceutical. Since the specific activity of the radiolabeled carrier molecules should be high, the “no‐carrier‐added radionuclides” have significant roles in nuclear medicine. Many researchers illustrated no‐carrier‐added 177Lu production; among these separation techniques such as ion exchange chromatography, reversed phase ion‐pair, and electrochemical method, extraction chromatography has been considered more capable than other methods. In order to optimize the conditions, some effective factors on separation of Lu/Yb were investigated by EXC. The NCA 177Lu, produced by this method, was mixed with 300μ1 of DOTMP solution (20 mg in 1 mL of 0.5 M NaHCO3, pH=8) and incubated under stirring at room temperature for 45 min. Radiochemical purity of the 177Lu‐DOTMP complex was determined using radio‐thin‐layer chromatography (RTLC) method. The complex was injected to wild‐type rats and biodistribution was then studied for seven days. The NCA 177Lu was produced with specific activity of 48 Ci/mg and with a radinuclidic purity of 99.99% through irradiation of enriched 176Yb target (1 mg) in a thermal neutron flux of 4×1013 n.cm−2.normals−1 for 14 days. 177Lu‐DOTMP was obtained with high radiochemical purities (>98%) under optimized reaction conditions. The radiolabeled complex exhibited excellent stability at room temperature. Biodistribution of the radiolabeled complex studies in rats showed favorable selective skeletal uptake with rapid clearance from blood along with insignificant accumulation within the other nontargeted organs.PACS number(s): 87.57.un, 87.57.uq
