Abstract: Orthogonal test was used to study the osmium removal from ruthenium absorption liquid in RPBR（rotating packed bed reactor）via oxidation and vacuum degassing. Effects of reaction temperature，H2O2 dosage，rate of liquid flow and RPBR rotating speed for the oxidation and degassing of osmium were investigated. Results showed that these factors are in the order of H2O2 dosage，reaction temperature，rate of liquid flow and RPBR rotating speed. These results provided a theoretical basis for the preparation of ruthenium hydrochloric acid solution with osmium in ppm using RPBR via oxidation and vacuum degassing.

摘要： 研究了超重力氧化-真空脱气方法从一次钌盐酸吸收液中选择性氧化-真空脱气赶锇，以反应温度、H2O2反应用量、液体流量和超重力旋转填料床反应器（RPBR）转速为影响因素，选用L9(34) 进行正交试验研究。考察了各因素对赶锇效率影响的程度。实验结果表明：各因素对赶锇率影响的显著性顺序为：H2O2反应当量倍数＞反应温度＞液体流量＞RPBR转速。这为RPBR高效氧化-真空脱气赶锇、制备含锇量为ppm级的钌盐酸溶液提供了理论依据。
