Catalytic reduction and carbon adsorption for removing free chlorine from water

摘要：

The removal of free chlorine was accomplished by physical adsorption and chemical reaction;adsorption was the main removal mechanism initially while chemical reaction was responsible for continued removal of free chlorine after adsorption equilibrium would have been established.Removal of flee chiorine was enhanced by:a longer contact time,a lower pH,and a higher initial/influent free chlorine concentration.The order of carbons’capacities for free ehlofine was the saine as the order of their phenol numbers.The coal activated carbon was the most reactive with free chlorine.followed by the fruit and coconut shell carbons.Much more free chlorine was removed in carbon columns than the carbon’s adsorptive capacity.
