Chromium is one of many heavy metals that used in many industrys. Wastewater will always contain Cr(III) because of industry’s activity. Recovery of Cr(III) to reuse it in industry can be done. Recovery Cr(III) with adsorption by magnetite coated ionic imprinted polymer supposed to be done. Anthranilic acid is allegedly can be used as a ligand for Cr(III) imprinted polymer because it can form complex with Cr(III) and also can be polymerized with formaldehyde. In this study, magnetite coated Cr(III) imprinted polymer from anthranilic acid was synthesized (mIIP). Complex Cr(III)-anthranilic acid form with composition 1:3. Polymerization was done by formaldehyde as crosslinking agent and HCl as catalyst. Magnetite coated polymer from anthranilic acid without Cr(III) template was also synthesized. These products characterized with FTIR and TEM. Imprinted polymer’s infrared spectrum show bands at 538 cm-1, 1436 cm-1, 1678 cm-1, 3350 cm-1, 3628 cm-1, 2858 cm-1 and 2926 cm-1 which are respectively indicate the presence of Fe-O, -CH2-(bending), C=O, -OH, -NH2, and -CH2-(stretching). Non- imprinted polymer’s infrared spectrum also show bands at 530 cm-1, 1442 cm-1, 1716 cm-1, 3344 cm-1, dan 3626 cm-1, 2854 cm-1 and 2926 cm-1 which also are respectively indicate the presence of Fe-O, -CH2-(bending), C=O, -OH, -NH2, and -CH2-(stretching). TEM images from these products show magnetite are coated by polymer in mNIP and mIIP.
