Abstract
We studied the Chromium (VI)removal capacity in aqueous solution by the biomass of Mangifera indica shell, using the diphenylcarbazide method to evaluate the metal concentration. Therefore, the highest biosorption of the metal (50 mg/L) occurs within 70 seconds, at pH of 1.0, and 28°C, with 1 g of biomass. At the analyzed concentrations of Cr (VI),biomass showed good removal capacity, besides it removes efficiently the metal in situ (100% of removal, 6 days of incubation, 5 g of biomass, in soil and water contaminated, respectively).So it can be used to eliminate it from industrial wastewater.
