Detection ability for specific metal ions in complex matrices is so important, therefore the production of materials with the selective ability of extraction and separation for metal ions is a growing field with widespread usage and importance. Selective ion template polymers, for metal ions are the means to achieve this goal. In this thesis, ion-template polymer based on magnetic Graphene oxide has been used. For measure, inductively coupled plasma device has been used. In this research, ion template polymer of Cu2+, Ni2+, Pb2+, Co2+ and Cd2+ synthesis simultaneously which that used from (3-Aminopropyl) triethoxysilane (APTES) as a functional monomer and tetreathoxysilane (TEOS) as a cross-linker, 1.5 di-phenylcarbazone as a ligand and also it was produced in the presence of magnetic Graphene oxide substrate. Ion template polymer of Cu2+, Ni2+, Pb2+, Co2+ and Cd2+ was concentrate from very dilute solution and also the actual water sample of the city. Optimization was carried out on suitable conditions for extraction and washing such as: pH of ion contacting solution with polymer, contact time of ion solution with polymer, adsorbent amount, and also washing time, volume and concentration of acid in the washing solution has been done by the central composite design method. Optimum conditions: pH=5.83, adsorption time= 16/35 minutes, adsorbent amount= 20/95, desorption time= 16 minutes, volume of washing solvent= 4 ml, concentration of washing solvent= 1.8 molar was obtained. The selectivity for copper, cobalt, cadmium, nickel, lead compared to other cations was very high.
