Abstract
The uptake of lead (Pb2+), cobalt (Co2+) and manganese (Mn2+) metal ions on a synthesized ion exchange resin is performed. Para-phenol-resin is the new synthesized ion exchange resin is prepared from the polycondensation of Dioxaloyl Para sulphanilamide and phenol in the presence of 60% H2SO4 by weight of reactant and using glacial acetic acid as a reaction medium at 60 oC. Formaldehyde solution is added dropwise to the reaction flask in a period of 3 hours and the reaction result is finally left for 8 hours at room temperature. The resulting resin containing sulphonate (-SO3H- ), and carboxylate (-COOH-) acid groups Para-phenolic-resin resin is used for the removal of Pb2+, Co2+, and Mn2+metals ions from aqueous solutions. To obtain the best heavy metal removal, batch sorption experiments are performed. Different variables are effecting the uptake of those heavy metals including, the change in the; pH, weight loading, aqueous metal ion concentrations and contact time intervals. Adsorption isotherms can be described by the Freundlich and Dubinin and Radushkevich (D-R) isotherm equations. Two kinetic models such as pseudo-first order and pseudo-second order equations are used to describe the rate of the metal ion adsorption.
