Development of cellulose-based biosorbents from the residue of the peach palm agribusiness and simulation of industrial scale-up for copper removal from Brazilian spirit.

Background: Cachaça (Brazilian spirit) is an alcoholic beverage of cultural and economic importance in Brazil. Its artisanal production is usually conducted in copper alembics, which results in contamination. The development of effective biosorbents from cheap matrices is an alternative to minimize both solid waste generation and copper levels in cachaça.
