<b>Copper ions remotion from sugarcane spirit by activated carbon and ion exchange resins</b> - doi: 10.4025/actascitechnol.v33i1.7751

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.
