Abstract: We studied the removal capacity of Chromium (VI) in solution by the grapefruit shell, using the diphenylcarbazide method to evaluate the metal concentration. So, the highest biosorption of the metal (50 mg/L) occurs within 70 minutes, at pH of 1, and 28 °C. According to temperature, the highest removal was observed at 60°C, in 180 minutes, when the metal (1 g/L) is completely adsorbed. At the concentrations of Cr (VI) analyzed, grapefruit shell, showed excellent removal capacity, besides, removes efficiently the metal in situ, (100% removal, 7 days of incubation, 5 g of biomass), and after of 1 hour of incubation the studied biomass reduces 1.0 g of Cr (VI) with the simultaneous production of Cr (III), so it can be used to eliminate it from industrial wastewater.
