| Resumo(s): | A biosorption system for the removal of hexavalent chromium from contaminated effiuents that allows the reutilization of the recovered supports as catalysts is proposed. The system consists of Arthrobacter viscosus bacterium supported on NaY zeolite. After the treatment of the effiuents, the metal-zeolite can be used in oxidation reactions. This work reports the optimized biotreatement conditions that lead to Cr-loaded in Na Y zeolite, which was tested as catalysts in the liquid-phase oxidation of cyclohexene. A comparison is made with a Cr-NaY zeolite prepared by the usual ion-exchange method. |
