Abstract

Molecularly Imprinted Polymer (MIP) melamine has been developed using the coolingheating method. Melamine as a template is inserted into ethanol and aquabides solvents, then added methacrylic acid (MAA) as monomer, ethylene glycol dimethacrylate (EDMA) as cross-linker and benzoyl peroxide (BPO) as initiator. The polymer solution is then stirred at 40 oC for 15 minutes. The solution is then inserted into the vial and the vial is closed and inserted into the freezer for 1 hour. After that, the vial is inserted into the furnace for 75 oC held for 3 hours then the temperature is raised to 80 oC for 3 hours then the temperature is raised to 85 oC for 1 hour to become a solid polymer. The solid polymer is then ground to a fine powder. The polymer powder was characterized by using FTIR and SEM. After that melamine template are washed from solid polymer. Disposal of melamine template is done with 3 treatments, each treatment is differentiated solvent type and time of washing. After disposal of the template, polymer powder are called as MIP. FTIR graph results show MIP treatment 2 and treatment 3 only have 2 peaks at wavenumber 1000-1250 cm-1 and 1 peak at wavenumber 660-900 cm-1. While in MIP treatment 3 looks still have 3 peaks at wavenumber 1000-1250 cm-1 and 3 peaks at wavenumber 660-900 cm-1. SEM results showed that the number of cavities in solid polymer was 247 cavities, MIP treatment 1 was 318 cavities and MIP treatment 2 was 438 cavities. These results indicate that MIP treatment 2 is more optimal than treatment 1. The results showed that ethanol solvent binds melamine better than methanol and the results of the removal process of melamine template using repeated times will produce a more optimal MIP.
