The adsorption of Fe (III) metal ions in water media using the ionic imprinted polymer has been carried out with a polyeugenol base polymer and poly(ethylene glycol) diglycidyl ether (PEGDE) as the crosslinking agent. The adsorbent is in the form of Ionic Imprinted Polymer Fe (IIP-Fe), and Non-Imprinted Polymer (NIP) was also used as a comparison. The polymer results are characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX), and Fourier Transform Infrared (FTIR). The adsorption test was performed to obtain the adsorption kinetics by varying the contact time. Meanwhile, adsorption isotherm was performed by varying the concentration of adsorbate, and adsorption selectivity between binary metal ions of Fe(III)/Cr(III), F(III)/Zn(II), and Fe(III)/Ag(I). Also, the adsorption mechanism was studied using different solvents such as HCl, Aquadest, KNO 3 , and Na 2 EDTA. The results of the filtrate in the adsorption test were characterized using AAS. The results showed the optimum time in kinetics was 60 minutes, the adsorption isotherm followed the Langmuir model with a large adsorption capacity of 23.640 mg/g on IIP-Fe and 17.636 mg/g on NIP. Adsorption selectivity towards Fe (III) metal ions in binary metal ions shows results in the order of Fe(III)/Zn(II)>Fe(III)/Cr(II)>Fe(III)/Ag(I), while the adsorption mechanism was dominated by hydrogen bonds.
