Osmium removal from ruthenium absorption liquid in rotating packed bed reactor via oxidation and vacuum degassing

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.
