Abstract:This paper described the preparation of precious metal catalysts by the impregnation method,which can be used in wet air oxidation (CWAO) for treating spent ion-exchange resin,and through screening Ru/TiO2,among the prepared catalysts,was selected as the best one because of its superior activity and good stability.Furthermore,experiment with Ru/TiO2was conducted to study the influences of various reaction conditions on the CWAO process in treating spent ion-exchange resin.The experimental results indicated that the reaction parameters such as temperature,initial O2 pressure,reaction time,the resin form (powder or granular),and stirring intensity affected the CWAO process to different degrees,and among others,the reaction temperature and initial O2 pressure were the key factors.
