Removing of Toxic Cr (VI) Ions from wastewater using different adsorbents.
The removal of hexavalent chromium from wastewater on the Na-bentonite and activated carbon has been studied under static conditions. Experiments were carried out as a function of solution pH, dosage of Na-bentonite and activated carbon contact time, agitation speed and temperature. The adsorption e...

| description | The removal of hexavalent chromium from wastewater on the Na-bentonite and activated carbon has been studied under static conditions. Experiments were carried out as a function of solution pH, dosage of Na-bentonite and activated carbon contact time, agitation speed and temperature. The adsorption equilibrium for hexavalent chromium on to Na-bentonite is reached in 120 min. the adsorption of hexavalent chromium is pH dependent in the pH range 1-4, the kinetic process of adsorption can be described by the pseudo-second order kinetic equation excellently and the adsorption isotherm be fitted to the langmuir and freundlich model by means of regression analyses very well. Finally it can be seen that Na-bentonite was favorite to be effective for removal of hexavalent chromium than activated carbon under the same experimental conditions. |
