A procedure based on radiochemical neutron activation analysis was developed for the determination of chromium in biological materials. The procedure consists of irradiation of reference and test samples in a nuclear reactor, microwave sample digestion, selective and quantitative radiochemical separations of chromium and gamma-ray spectrometric measurement of Cr. Separation of chromium from the accompanying elements was done on the column packed with inorganic resin MnO Resin. Distribution coefficients of Cr, Zn, Co, Cs and Sc were determined in the system: MnO Resin-HCl, HNO and HSO. Accuracy of the procedure was checked by analysis of certified reference materials.
开发了一种基于放射化学中子活化分析的方法，用于测定生物材料中的铬。该方法包括在核反应堆中对参考样品和测试样品进行辐照、微波消解样品、铬的选择性和定量放射化学分离以及铬的γ射线光谱测量。在填充有无机树脂MnO树脂的柱上进行铬与伴随元素的分离。在MnO树脂-HCl、HNO和HSO体系中测定了Cr、Zn、Co、Cs和Sc的分配系数。通过分析有证标准物质检验了该方法的准确性。
