Pengaruh pH dan Waktu Terhadap Kemampuan Adsorpsi Mip_TFMAA-co-Egdma
ABSTRACT: A molecularly
imprinted polymers (MIP) can be synthesized using functional monomers and
template molecules through polymerization with the aid of cross linker. In
previous studies, MIP_TFMAA-co-EGDMA was synthesized using the main ingredient
tryfluoromethylacrylic acid (TFMAA) as functional monomer, b-sitosterol as a
template molecule and ethyleneglycol dimethacrylate (EGDMA) as cross linker.
The ability of adsorption against the effects of pH and contact Time of MIP has
been evaluated. Variations of pH standard solution b-sitosterol were 4, 5, 6,
and 7, while the time variation used were 30, 60, 90, and 120 minutes. The data
of b- sitosterol concentrations adsorbed by MIP_TFMAA-co-EGDMA because of the
influence of pH and contact times were analyzed using high pressure liquid chromatography (HPLC). pH5 gives the most
influence on the adsorption capacity MIP_TFMAA-co-EGDMA against b-sitosterol.
The number of b-sitosterol adsorbed on the pH was 1.0265 mg/g, while at 90
minutes was the best time for the MIP b- sitosterol adsorb as much as 1.3486
mg/g. Based on the adsorption kinetics study, the adsorption ability
MIP_TFMAA-co-EGDMA against b-sitosterol in accordance with the pseudo second
order kinetic model.
