Abstract

Chromium (Cr) is one of the elements presents in crust of the earth. Due to its toxicity, chromium is considered as water contaminant that may disturb metabolic activity. In the present study, ADSORPTION of dissolved Chromium (VI) onto ELAEAGNUS ANGUSTIFOLIA FRUIT CHARCOAL, JUJUBE FRUIT CHARCOAL and the standard GRANULAR ACTIVATED CARBON (GAC) has been investigated and compared. The effect of contact time, pH value, initial concentration of dissolved Chromium and amount of adsorbent on the ADSORPTION of Cr were investigated by the mentioned adsorbents. Results showed that the ADSORPTION process was highly dependent on pH. Maximum Cr removal was achieved when the pH of the mixture fell within 2. ADSORPTION test results revealed that Cr ADSORPTION on the studied adsorbents could be better described by Longmuir isotherm. Maximum Cr removal efficiencies were obtained by ELAEAGNUS ANGUSTIFOLIA FRUIT CHARCOAL, JUJUBE FRUIT CHARCOAL and GAC 1.66 mg/g, 35 mg/g, 66 mg/g. Based on Cr (VI) removal efficiency, it is concluded that jujube powder could be considered as one of the natural and inexpensive adsorbent to remove Cr (VI) from aqueous solution.
