Removal of Metal Ions by Using New Composite Ion-Exchangers

Abstract

Phenol – formaldehyde resin (PFR) was prepared and blended with sulphonated charcoals (SCs) prepared from Crateva Nurvala Carbon. Composite ion exchange resins (IERs) were preparedby varying the amount of SCs (10-50%w/w) in the blends. All the important physico - chemical properties, effect of initial concentration of metal ion has been done. Composites up to 20% (w/w) blending retain almost all the essential characteristics and Cation Exchange Capacity (CEC) of the original PFR. It is concluded that blending of PFR by SCs will reduce the cost of IERs.
