Abstract

The use of epichlorohydrin to improve the stability of chitosan adsorbent has been carried out. The purpose of this study was to determine the stability of the chitosan adsorbent after modified into epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Adsorbent prepared by homogeneous gel formation of chitosan in acetic acid medium and then modified into epichlorohydrin cross-linked chitosan beads and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. Stability of the adsorbent was determined by calculating the percentage of insoluble material after stirring the adsorbent in nitric acid medium at pH 1, 2, and 3 for 12 hours. The results of FTIR spectra show a shift of the absorption band of chitosan were compared with epichlorohydrin cross-linked chitosan and ionic cobalt imprinted adsorbent chitosan cross-linked epichlorohydrin. The use of epichlorohydrin as cross-linked agent may increase the stability of the adsorbent to maintain the percentage of insoluble material by 89% at pH 3 for epichlorohydrin cross-linked chitosan adsorbent and 96% at pH 3 for ionic cobalt imprinted adsorbent chitosan  cross- linked epichlorohydrin.

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.
