Selective separation of heavy metals using natural Jordanian zeolite

Y. Taamneh*, Jordan University of Science and Technology, Jordan

The major industrial sources impact the environment as a result of producing heavy metals. The existence of heavy metals in wastewater due to many manufacturing processes is a legalized problem worldwide. Most common industrial sources of heavy metals obtained from surface treatment processes as well as industrial products that ends up in wastewater. Removing heavy metals from industrial wastewater required high energy or special operational requirements. Several techniques such as adsorption, extraction, coagulation, precipitation, ion-exchange, electrochemical methods, membrane processes, and biosorption have been supposed for the treatment of wastewater pollution. Adsorption method form an appropriate method for wastewater treatment due to its cost effectiveness and simplicity, among all these methods. Actually, natural zeolite gains progressive attention of many investigator due to its special characteristic such as ion exchange capacity, hydration-dehydration, and adsorption. Zeolites are aluminosilicate minerals of alkali or alkaline earth metal which contains crystal water. Zeolites consist of three dimensional networks of AlO4 and SiO4 tetrahedra linked by sharing of all oxygen atoms. The voids make up from 20 to 50 % of the total crystal volume of most zeolites. For wastewater treatment, the most important properties of natural zeolite are cation exchange capacity and ion selectivity

Natural Jordanian zeolites has been used for the removal of some heavy metals like cadmium and copper from aqueous solution. In this work our aim object is to measure the cadmium and copper isotherms and kinetic for a wide range of concentration....
