苏联科学院无机和分析化学研究所的沙比洛娃等研究了硝酸和盐酸对原子吸收光谱法测定钇的影响,以及铜、钡和钇的相互干涉。确定了最佳测定条件,建立了高温超导化合物YBa_2Cu_3O_x中Y、Ba和Cu的测定方法,测定结果的相对标准偏差不大于0.02。测定方法:超导金属氧化物试料100mg溶解于5ml浓硝酸和1ml浓盐酸中,溶解 The impact of nitric acid and hydrochloric acid on the determination of yttrium by atomic absorption spectrometry and the mutual interference of copper, barium and yttrium have been studied by Sabilovar et al. Of the Institute of Inorganic and Analytical Chemistry at the Soviet Academy of Sciences. The optimum determination conditions were determined and the determination methods of Y, Ba and Cu in YBa_2Cu_3O_x were established. The relative standard deviations of the results were not more than 0.02. Determination: Superconducting metal oxide sample 100mg dissolved in 5ml of concentrated nitric acid and 1ml of concentrated hydrochloric acid, dissolved
