Remoção de íons de cobre de aguardente utilizando carvão ativo e resinas de troca iônica

Abstract

Sugarcane spirit (aguardente) is the most important fermented/distilled beverage in Brazil. If the concentration of cooper (Cu2+) in sugarcane spirits was less than 2.0 mg L-1, it could be exported to several European countries. This study showed that the sugarcane spirits contaminated with these ions with a concentration of 4.0, 7.0 and 9.0 mg L -1 can be recovered using both active carbon and ion-exchange resins, reusing these absorbent materials. When the concentration of Cu2+ is equal to 9.0 mg L-1, active carbon can be reused up to 3 times and ion-exchange resins up to 7 times.
