Synthesis of Fe Ionic-Imprinted Polyeugenol Using Polyethylene Glycol Diglycidilether as Cross-Linking Agent for Sorption of Fe(III)

Abstract

Fe-Ionic Imprinted Polymer (IIP) from polyeugenol as base polymer and polyethylene glycol diglycidyl ether (PEGDE) as cross-linking agent had been synthesized to adsorb Fe(III) from aqueous media. The non-imprinting material (NIP) and polyeugenol were used in the adsorption study as control. Synthesis work included polymerization, template uploading, crosslinking and template removal, optimized for different template ion upload pH and concentrations. The polymers were characterized by FTIR spectroscopy, XRD and SEM-EDX, followed by adsorption test to study the adsorption kinetics and isotherms for all adsorbents. Selective adsorption study of IIP was carried out using binary mixtures of Fe(III) and Cr(III), Pb(II), Cd(II). Experimental results showed that the optimum conditions for the synthesis was template upload pH of 3, Fe/polyeugenol ratio of 1 mg/g, while the optimum adsorption pH was 3. The adsorption mechanism of Fe(III) on all adsorbents was dominated by hydrogen bond formation. The adsorption kinetics followed the pseudo-second-order model while the equilibrium data was best explained by the Langmuir isotherm model. The adsorption capacity of Fe(III) on the IIP was 12.73 mg/g, higher than that of the other adsorbents. Results also show that IIP-Fe was more selective toward Fe than NIP by 2.69 (Cd), 1.66 (Cr) and 1.6 (Pb) fold, respectively.

In-Situ Ionic Imprinted Membrane (IIM) Synthesis Based on Acetic Polyeugenoxy Acetyl Tiophen Methanolate for Gold(III) Metal Ion Transports

“…PEGDE is applied as a crosslinking agent as well as a plasticizer, which will increase the mechanical strength of the membrane. Based on previous studies, PEGDE crosslinked PVA based membranes have been shown to have good mechanical strength as indicated by the results of tensile strength tests [15][16].…”

“…The crosslink reaction in the IIM manufacturing process here, in addition to adding polymer chains and increasing the mechanical strength of the membrane, also plays a role in locking the Au 3+ metal ion template on the PEATM polymer, so that an appropriate imprint will be formed [16]. Fig.…”

Pengaruh Jumlah Mol Kroslinker Pada Selektifitas IIP Berbasis Polieugenol Terhadap Fe(III)

“…IIP 3 mol menghasilkan luas area 0,00 m 2 /g kemungkinan dikarenakan polimer yang mengalami shrinkage (penyusutan) yang mengakibatkan luas permukaannya sangat kecil. Penurunan luas permukaan ini dialami oleh peneliti lain diantaranya Buhani et al (2010), Djunaidi et al (2015), dan lain-lain.…”

Computational Approach to Evaluate Eugenol Affinity and Derivatives Empirical Against Cu(II)

“…The content of eugenol in cloves ranges from 60-90% (Sneddon, 1997). Eugenol is an Indonesian natural ingredient that can be used for the separation of metal ions (Djunaidi, Jumina, Siswanta, & Ulbricht, 2015;. Eugenol is used as a starting material for the synthesis of a compound because there are three functional groups that are bound to it, namely the allyl, hydroxyl and methoxy groups that can potentially work as functional monomers for the selective adsorption process of Cu (Djunaidi, Wibawa, & Murti, 2018).…”
