Abstract

Purpose: This study aimed to analyze the effects of removal of hexavalent Chromium using carbonated almond green hulls. In the present study, derived carbon fromalmond green hulls of zonal district of Iran were used to remove hexavalent Chromium from Synthetic wastewater. Materials and Methods: The effects of pH (2-10), Adsorbent dose (2-24 g/L), Cr (VI) concentration (10-100 mg/L), Contact time (1-60 min) and temperature (5-50°C) were studied. The experimental data fitted well to Langmuir isotherm (R2 = .853; maximum adsorption capacity 1.90 mg/g). At the end, to assess hexavalent Chromium, Spectrophotometer UV/VIS Spectrometer T80+ at 540 nm wavelength was used. Results: The findings of the present study revealed that hexavalent Chromium removal was highly dependent on the pH. Surprisingly it was understood that due to limited space in the adsorbent, the increase in the initial hexavalent Chromium density caused the removal efficiency to decrease. Conclusion: Carbonated almond green hull does efficiently remove hexavalent Chromium from industrial water wastes.
