Abstract EN
This research describes the removal of Cr (VI) ions by adsorption on date palm fibers.
This plant is locally available in Iraq and nearby countries.
Date palm fibers have porous structure as well as rich in carboxyl, hydroxyl, and carbonyl groups which cause the adsorption process.
The biosorption of Cr (VI) ions from aqueous solutions by date palm fibers was studied in a batch experiments as a function of, contact time, metal ion concentration, mass of adsorbent and shaking speed.
The adsorption data fit well with Langmuir adsorption isotherm model rather than Freundlich model.
The adsorption percent was found to be about 93% when the operating parameters are: mixing speed 250 rpm, particle size 100-200 µm, initial chromium ions concentration of 100 ppm and adsorbent concentration 20 g/L.
Two isotherm models were tested; Langmuir and Freundlich.
Experimental data was found fitted well by Langmuir equilibrium isotherm model.
