Breakthrough Studies of Biosorption of Cr (VI) and Cu (II) from Aqueous Solutions Using Eucalyptus cameldulensis Charcoal through Column Operations
Journal Title: Universal Journal of Environmental Research and Technology - Year 2012, Vol 2, Issue 3
Abstract
In the present article, the potential of Eucalyptus cameldulensis charcoal for the biosorption of Cr (VI) and Cu (II) ions from aqueous solutions using fixed bed column operations was investigated. Eucalyptus cameldulensis charcoal was activated using 1.0N HCl. The different parameter investigated in this study include bed depth (16.0, 20.0 and 24.0 cm), flow rate (1.0, 1.5 and 2.0ml min-1) and initial metal ion concentration (100, 150 and 200mgL-1).The maximum percentage removal for Cr (VI) and Cu (II) were 66.32% and 57.69 % at 24.0 cm bed depth with 1.0 ml min-1 flow rate and 100 mgL-1 initial metal ion concentration. The bed depth service time model (BDST) was successfully applied to the column studies and the biosorption capacity (No) obtained for Cr (VI) and Cu (II) were 100.0 mg L-1 and 87.5 mg L-1respectively. The exhausted columns were regenerated using 0.5N NaOH after each biosorption cycle. Column studies demonstrate that charcoal prepared from Eucalyptus cameldulensis has significant capacity for the removal of Cr (VI) and Cu (II) from aqueous solutions.
