Abstract:
Pyrogallol-imprinted polymers (PIPs) were prepared using molecular imprinting
:
approach. Pyrogallol usually can be found in natural herbs plants such as Kacip
Fatimah (Labisia pumila). In this study, pyrogallol has been used as a template
molecule. Pyrogallol-imprinted polymers (PIPs) and non-imprinted polymers (NIPs)
were synthesized via precipitation polymerization using three different monomers;
methacrylic acid (MAA), methyl methacrylate (MMA) and 4-vinylpyridine (4-VP)
in order to determine the most suitable functional monomer for adsorption of
pyrogallol. The synthesized polymers were characterized by Fourier Transform
Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Brunauer-
Emmett-Teller Analysis (BET) and UV-Visible Spectroscopy (UV-Vis). As the
results, by increasing the adsorbent dosage, adsorption of pyrogallol onto the PIPs
increased and the contact time is prolonged. Equilibrium adsorption isotherm studies
are the study of binding properties and description of the interactions between
adsorbent and adsorbate which give adsorption capacity of an adsorbent towards
