Tách biệt 95Zr và 95Nb khỏi nhau và các sản phẩm phân rã khác bằng phương pháp hấp phụ và desorption trên gel silica sử dụng dung dịch axit hydrochloric Dịch bởi AI
Journal of Radioanalytical and Nuclear Chemistry - Tập 60 - Trang 149-158 - 1980
E. Roy Clark, Kawther A. Al-Zubaidi, H. Al-Shahristani
Hành vi hấp phụ của gel silica đối với zirconium, niobium, ruthenium và cerium trong axit hydrochloric đã được nghiên cứu bằng cả phương pháp batch và cột. Một phân tách đồng vị phóng xạ thỏa mãn giữa zirconium và niobium, cũng như giữa chúng với các sản phẩm phân rã khác đã được thực hiện bằng kỹ thuật hai cột. Quy trình được khuyến nghị bao gồm việc hấp phụ tất cả các nuclide trên một cột gel si...... hiện toàn bộ

Comparison of neutron activation analysis with conventional detection techniques for the evaluation of trace elemental contamination in Mallard (Anas platyrhynchos) feathers
Journal of Radioanalytical and Nuclear Chemistry - Tập 287 - Trang 471-478 - 2010
Stacey D. Haskins, David G. Kelly, Ron D. Weir
Instrumental neutron activation analysis (INAA) was used to determine trace elemental contamination in bird feathers. Primary feathers from twelve mallard (Anas platyrhynchos) ducks, migrating through the Thousand Islands region of Ontario, Canada, were analyzed for selenium, mercury, chromium, arsenic and antimony. Certified reference materials were used to assess the quality of the analytical pr...... hiện toàn bộ
Chemical bonds in ion implanted structures
Journal of Radioanalytical and Nuclear Chemistry - Tập 190 - Trang 225-235 - 1995
I. Dézsi
The physical processes of ion implantation are discussed. The chemical bonds between implanted and host atoms depend on the location of the implanted atom in the lattice. The experimental methods used for the investigation of the bonding structure are shortly revlewed. The Mössbauer spectroscopy had proved a powerful method for determining the bonding structures of the implanted atoms. The discuss...... hiện toàn bộ
Studies on dynamic dissociation constant of 99Mo–insulin complex
Journal of Radioanalytical and Nuclear Chemistry - Tập 292 - Trang 859-862 - 2011
Swadesh Mandal, Susanta Lahiri
In this article we studied the dynamic dissociation constant (k d) of 99Mo complexed with insulin molecule at various pH. The k d values were determined by dialysis technique against deionised water. The T 1/2 of the molybdenum–insulin complexes were found to be 6.41, 5.25 and 3.5 h at pH 5, 6 and 7 respectively. The half-lives indicate that insulin ...... hiện toàn bộ
Slab-gel electrophoresis of commercial iodine-125 fibrinogen
Journal of Radioanalytical and Nuclear Chemistry - Tập 65 - Trang 349-353 - 1981
P. H. Waterhouse, J. R. McLean
The deposition of125I in three commercial preparations using polyacrylamide slab gel electrophoresis is studied.
Simplified method for determining radiochemical purity of 99mTc-TRODAT-1
Journal of Radioanalytical and Nuclear Chemistry - Tập 277 - Trang 591-594 - 2008
Z. P. Chen, S. P. Wang, J. Tang, X. M. Li, C. Y. Liu, X. J. Xu, G. X. Cao
To provide a convenient and facile method to evaluate the radiochemical purity (RCP) of 99mTc-TRODAT-1 in quality control of routine clinical application, a simplified method of single-strip thin layer chromatography (TLC) was developed and validated by high performance liquid chromatography (HPLC). The RCP data of TLC correlated well with HPLC.
An effective magnetic amorphous titanium phosphate material to remove U(VI) from water: synthesis, characterization, and adsorption properties
Journal of Radioanalytical and Nuclear Chemistry - Tập 331 - Trang 4705-4719 - 2022
Lin Cheng, Wenzheng Cui, Zhongpin Cheng, Youqun Wang, Lin Xu, Zhibin Zhang, Lei Chen, Qie Luo, Xiaohong Cao, Yunhai Liu
The material of magnetic amorphous titanium phosphate (MATP-x-T, where x was the dosage of Fe3O4, T was synthesis temperature) was successfully synthesized and confirmed by various experimental characterization methods (FT-IR, XRD, SEM, and Zeta potential), and its adsorption property for U(VI) removal was evaluated. The adsorption of U(VI) on MATP-x-T were explored through batch experiments. The ...... hiện toàn bộ
Determination of rare earth elements in Taiwan monazite by chemical neutron activation analysis

Mössbauer study of iron carbide nanoparticles produced by sonochemical synthesis
Journal of Radioanalytical and Nuclear Chemistry - Tập 303 - Trang 1503-1506 - 2014
R. Miyatani, Y. Yamada, Y. Kobayashi
Iron carbide nanoparticles were produced by ultrasonication of ferrocene in diphenylmethane and their properties were investigated using Mössbauer spectroscopy, Transmission electron microscopy and X-ray diffraction. The as-prepared particles were amorphous paramagnetic iron carbides, and the particles obtained after annealing exhibited magnetic components. The particles obtained after annealing a...... hiện toàn bộ
