Abstract: We studied the Chromium (VI) removal capacity in aqueous solution by newspaper, using the diphenylcarbazide method to evaluate the metal concentration. So, the highest biosorption of the metal (50 mg/L) occurs within 24 hours, at pH of 1, and 28 °C. According to temperature, the highest removal was observed at 60 °C, in 5 hours, (100%). At the analyzed concentrations of Cr (VI), the newspaper showed good removal capacity, besides it removes efficiently the metal in situ (83.1%, and 93.9% of removal, 7 days of incubation, 5 g of biomass, in soil and water contaminated, respectively). So, it can be used to eliminate it from industrial wastewater.
