| Abstract | ||||
| The aim of the current research is to study the feasibility and the efficiency of synthetic Resin Amberjet-4200 and Dowex-50in the removal of divalent ions Mg (II), Mn (II), Zn (II) and Pb (II) ions from wastewater. The research consisted of three phases; a preliminary comparative study, batch equilibrium tests and fixed-bed column tests. The main considered points from the three phases of the research are summarized as follows: * It has been noted that the removal efficiency of Mg (II), Mn (II), Zn (II) and Pb (II) ions by the synthetic resins of Dowex50 and Amberjet-4200 in phase I of the research, these synthetic resin has yielded the highest removal of 83.5%, at a dose of 3g/l and pH 5.4. * Treatment using acid has increased the removal efficiency of from83.5% to 94.50%, which was the highest percent removal achieved among all the studied resins. * Treatment using alkaline as KOH prior to tartaric acid treatment did not prove any enhancement in the removal of Mg (II), Mn (II), Zn (II) and Pb (II) ions, as TA-N-SB has only yielded 66.14% uptake, compared to 88.50% by these resins. Therefore, a OH treatment is considered a dispensable step in the treatment process. * Each of them or the separate one of Dowex-50 achieved very high removal efficiency; however, their high alkalinity would limit their industrial applications. * Amberjet-4200 is considered the most promising sorbent for the uptake of Mg (II), Mn (II), Zn (II) and Pb (II) due to its high efficiency, economic feasibility, and simplicity of preparation | ||||
