So, the highest biosorption of the metal (50 mg/L) occurs within 100 minutes, at pH of 1.0, and 28¡ãC. According to temperature, the highest removal was observed at 60¡ãC, in 11 minutes, when the metal (1 g/L) is completely adsorbed. At the analyzed concentrations of Cr(VI), lemon shell, showed excellent removal capacity, besides it removes efficiently the metal in situ (97.2% removal, 7 days of incubation, 5 g of biomass). After 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. %K Chromium(VI) %K Biosorption %K Remotion %K Biomass %K Chromium(III) %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=21156
