Lead ion (Pb(II)) has been known as a dangerous pollutant and has various negative impacts on humans in the long run due to its non-biodegradable properties and can be accumulated inside human bodies. One of the case can be seen in the contamination of Citarum River, which shows that 127 km or 47,1& of the total length of of the river is heavily polluted by lead ion that contains around 0,01 – 0,08 ppm. This surpassed the threshold that has been set by Permenkes RI Nomor 492/MENKES/PER/IV/2010, which is around 0,01 ppm. This research proposed a removal method using ion imprinted polymer (IIP). Synthesis of polymer is done by using methacrylic acid as a functional monomer, Pb(II) ion as a template, ethylene glycol dimethacrylate as a crosslinker, and azodiisobutyronitrile as an initiator. In this research, the synthesis of non-imprinted polymer is also done to compare the adsorption performance. Characterization using FTIR shows no significant difference between IIP and NIP spectrum. Adsorption test using contact time as the parameter shows that NIP is best performed at 120 minutes contact time, while contact time for IIP can not yet to be determined. One of the factors that can cause this is presumably the weak interaction between the template ions and the polymer matrix that affects the formation of the imprinting sites. Literature research shows that adding a complexing ligand can form a better performed IIP materials.
