Removal of heavy metals from stainless steel effluents by waste biomass from Brazilian alcoholic beverage production

The capacity of waste biomasses from sugar-cane aguardente, a traditional Brazilian spirit, for metal biosorption was assessed. Free biomass and biomass immobilized onto chitin and Dowex (ion-exchange resin) were utilized to remove chromium, iron and nickel from both synthetic solutions and stainles...

Zusammenfassung:	The capacity of waste biomasses from sugar-cane aguardente, a traditional Brazilian spirit, for metal biosorption was assessed. Free biomass and biomass immobilized onto chitin and Dowex (ion-exchange resin) were utilized to remove chromium, iron and nickel from both synthetic solutions and stainless steel effluents. The best performance in terms of metal sorbed was observed in with free biomass, with the following adsorption capacity: 70% chromium, 50% iron and 20% nickel at pH 4.0.[PUBLICATION ABSTRACT]
