Remoción de Cromo (VI) en Solución Acuosa por la Biomasa Celular de Paecilomyces sp.

The objective of this work was to determine the removal of Chromium (VI) on the Paecilomyces sp.; fungal biomass, spectrophotometrically using diphenylcarbazide as the complexing agent. The highest adsorption was obtained at pH= 1.0±0.2, at 50 o C after 16 hours of incubation, with 7.2 mg/200 mL of initial concentration of Chromium (VI) and 80 mg/200 mL of cellular biomass. It was concluded that application of this biomass on the removal of Cr (VI) in aqueous solutions can be used since 1 g of fungal biomass remove 100 mg/200 mL of this metal after three hours of incubation.
