HIGUERA COBOS, Oscar Fabián; FLOREZ GARCIA, Luis Carlos  and  ARROYAVE LONDONO, Juan Felipe. Studying chromium biosorption using arabica coffee leaves. Ing. Investig. [online]. 2009, vol.29, n.2, pp.59-64. ISSN 0120-5609.

This work was aimed at providing an alternative for removing heavy metals such as chromium from waste water (effluent) from the leather industry and galvanoplasty (coating with a thin layer of metal by electrochemical means), using coffee leaves as biomass. Using arabica coffee (Castle variety) leaves led to 82% chromium removal efficiency for 1,000 mg/L synthetic dissolutions in 4 pH dissolution operating conditions, 0 rpm agitation, 0.149 mm diameter biomass particle size and 0.85 g/ml biomass / dissolution volume ratio.

Keywords : chromium; coffee leaf (Castle variety); arabica coffee; biosorption.
