Syntheses and spectroscopic characterization of uranium(VI) silicate minerals
Journal of Radioanalytical and Nuclear Chemistry - Tập 275 - Trang 633-642 - 2007
S. Lehmann, G. Geipel, H. Foerstendorf, G. Bernhard
In this study, the secondary uranium(VI) silicate minerals boltwoodite, sodium boltwoodite and uranophane were synthesized. Sodium boltwoodite was successfully obtained by the following new reaction procedure. Their analytical characterization was carried out by means of inductively coupled plasma mass spectrometry and atomic absorption spectroscopy, scanning electron microscopy, X-ray powder diff...... hiện toàn bộ

B. E. Özdiş, N. F. Çam, B. Canbaz Öztürk
The radioactivity concentrations of 226Ra, 232Th and 40K in 42 samples from different types of cements produced in Turkey were measured using gamma-ray spectrometer. The determined values were 18–143 Bq kg−1 (226Ra), 5–66 Bq kg−1 (232Th) and 142–540 Bq kg−1 (40K). Additionally, the calculated radiological hazard parameters such as absorbed dose rate, annual effective dose, radium equivalent activi...... hiện toàn bộ

Recovery of 60Co and 137Cs with various solid phases from aqueous solutions of different chemical composition
Journal of Radioanalytical and Nuclear Chemistry - Tập 316 - Trang 869-884 - 2018

Removal of microamounts of 60Co and 137Cs from different aqueous solutions, included NPP trap waters and simulated NPP bottom residues, by coprecipitation with various solid phases was studied. It was showed that coprecipitation of 60Co and 137Cs with the solid phase of K+, Fe3+, and Ni2+ ferrocyanides formed by adding K4[Fe(CN)6], Fe(NO3)3, and Ni(NO3)2 ensures almost 100% removal of both radionu...... hiện toàn bộ
Adsorption of uranium(VI) from aqueous solution using phosphonic acid-functionalized silica magnetic microspheres
Journal of Radioanalytical and Nuclear Chemistry - Tập 310 - Trang 1155-1163 - 2016
Limin Zhou, Hongbin Zou, Yun Wang, Zhirong Liu, Zhiwei Huang, Taian Luo, Adesoji A. Adesina
The phosphonic acid-functionalized silica magnetic microspheres (PA-SMM) were successfully synthesized for U(VI) adsorption. The PA-SMM exhibited higher adsorption capacity for U(VI) compared to unmodified silica magnetic microspheres due to the high affinity of phosphonic acid groups with U(VI). The adsorption was dominated by inner sphere surface chelation and kinetically followed the pseudo-sec...... hiện toàn bộ

Decomposition rates of radiopharmaceutical indium chelates in serum
Journal of Radioanalytical and Nuclear Chemistry - Tập 53 - Trang 327-336 - 1979
S. M. Yeh, C. F. Meares, D. A. Goodwin
The rates at which six small aminopolycarboxylate chelates of trivalent111In and three protein-bound chelates of111In deliver indium to the serum protein transferrin have been studied in sterile human serum at pH 7.3, 37°C. Sterically hindered chelates containing a substituent on an ethylene carbon of EDTA decompose with rates in the range 0.03 to 0.11% per day—one to two orders of magnitude slowe...... hiện toàn bộ
