Abstract

Molecular imprinting is a versatile and facile method for preparing a synthetic polymer with a specific binding site for a specific template. The molecularly imprinted polymer (MIP) was produced by precipitation polymerization of solution containing a functional monomer (MAA), cross-linker (EGDMA) and template (Janus Green B). In this project, MIP was synthesized to remove the Janus Green B dye from water. Janus Green B is a dye that can contaminate the water. Then, the structural MIP was characterized by using Scanning Electron Microscopy (SEM), Fourier Transfrom Infrared (FTIR) spectroscopy and Brunauer, Emmett and Teller (BET). It was found out that the polymer that has been produced was spherical and regular in shape. The MIP has a higher surface area, pore volume and pore size compared to NIP due to the presence of template molecule. The rebinding efficiency of MIP and NIP was conducted by batch binding analysis and the analysis was performed by using uv-vis spectrophotometer. The result showed that the MIP has higher efficiency compared to NIP. The selectivity test also has been done by using methyl yellow as competitor species and it shows that the MIP was more selective towards Janus Green B compared to methyl yellow. The MIP was applied for the removal of Janus Green B dye from water. The removal efficiency of Janus Green B from tap water and river water were 98.89% and 98.80% respectively.
