Removal of hexavalent chromium using coffee husk

open access: yesInternational Journal of Environment and Pollution, 2010
The potential to remove chromium(VI) from aqueous solutions through biosorption using coffee husk was investigated. The effects of pH, contact time, initial concentration and adsorbent dosage on the adsorption of Cr(VI) were studied. The data obeyed Langmuir and Freundlich adsorption isotherms.
