| Abstract: | Cupric sulphate was prepared by furnacing, acidation, filtration and recrytallization from the waste catalyst for producing furfuryl alcohol by furfuraldehyde hydrogenization. Chromicalum was prepared by adding soda ash, furnacing and leaching from remnant settle on above step. The method is simple in techinics, low in cost and high in recovery. Recovery of cupric ion is more than 90% and that of chromic ion is more than 60%. Furthermore, cupric and chromic ions are recovered simultaneously. |
