ACOSTA, Ismael; CARDENAS, Juan F; ALVARADO-HERNANDEZ, Diana  y  MOCTEZUMA-ZARATE, María G. Removal of Chromium (VI) from Aqueous Solutions by Fungal Biomass of Paecilomyces sp.. Inf. tecnol. [online]. 2008, vol.19, n.1, pp.69-74. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000100009.

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^oC 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.

Palabras clave : biosorption of chromium; fungal biomass; water decontamination; colorimetry.
