| Abstract: | Preparation method of vanadium pentoxide from spent catalyst was described in this article.The method includes following steps:roasting spent catalyst,dissolving the roas ting product by sulfric acid,and extraction of V 2O 5 from leaching solution.The effects ofpreparation conditons such as composition of extractants,pH value of liquid phase and extractant dosage on recovery of vanadium pentoxide were studied.The experiment results indicated that the extraction rate of V 2O 5 can be more than 95% when extracting solution was consisted of a 30∶70 to 60∶40 mixture(by weight)of trialkylamine and kerosene,and volume ratio of organic phase and liquid phase was 0.4∶1? |
