“…Polieugenol, yang terbentuk dari proses polimerisasi eugenol memiliki gugus -OH dan cincin benzene (Kiswandono, 2016). Salah satu kegunaannya sebagai carrier dalam metode pemisahan logam yang cukup banyak digunakan pada industry maupun penelitian (Sudarlin & Haryadi, 2017). Berbeda dengan eugenol, pada polieugenol pada umumnya tidak memiliki gugus vinil serta biasanya berwujud padat atau gel tergantung dari proses polimerisasi, penelitian tentang polieugenol dengan katalis telah banyak dilakukan pada penelitian sebelumnya Seperti Suirta dkk., (2012) Fourier transform infrared (FTIR) adalah alat spektroskopi yang paling banyak digunakan untuk mengidentifikasi konstituen kimia dan untuk menjelaskan struktur senyawa dan sebagai metode hemat waktu dalam mengkarakterisasi atau mengidentifikasi gugus fungsional yang berdasarkan energi vibrasi dari mode ikatan kimia tertentu dalam senyawa atau bahan yang diperoleh secara sintetis atau secara alami (Chaudhary dkk., 2015).…”

Eugenol is a paleyellow oily liquid which can be extracted from essential oils such as clove and cinnamon oils. This study aimed to modify eugenol and to reduce environmental pollution caused by polymers by utilizing natural materials through polymerization of eugenol with concentrated nitric acid (HNO3) and media of acetic acid (CH3COOH). Various of acetic acid media used were 5%, 25%, and 50%. The result of polieugenol was blackish brown, in the form of shiny gels, smelling of cloves, and soluble in ethanol, slightly soluble in chloroform and insoluble in benzene and water. The product polieugenol was washed with aquades. The yields before washing were 142.75%, 141.25% and 138.75%, and the yield after washing were 88.265%, 88.397% and 87.248%. The Fourier Transform InfraRed (FT-IR) spectrophotometer results showed that the polymerization did not occur perfectly showing by absorption peaks of CH=CH2 and C = C groups at 995.27 and 1635.89 cm-1.

Ionic Imprinted Polymer (IIP) with polyeugenoxy acetate (PA) as the base polymer, EGDMA as the crosslinking agent, and AIBN as the initiator have been synthesized to adsorb Fe(III) metal ions. NIP (non-imprinted polymer) was used as a comparison for this study. The produced polymer was characterized using FTIR spectroscopy and SEM-EDX. Adsorption rate and capacity were examined through adsorption isotherm and kinetics studies for all adsorbents. The adsorption selectivity test was done with mixed-metal solutions of Zn(II), Cu(II), Cd(II), and Ag(I). The results of SEM analysis on IIP-PA show a more uniform and regular size than NIP-PA. Adsorption of Fe(III) in IIP-PA and NIP-PA follows pseudo-second-order kinetics, and the adsorption isotherm both follow the Langmuir theory. The adsorption capacity of Fe(III) metal ions in IIP-PA is 10.88 mg/g, and the adsorption capacity of NIP-PA is 7.94 mg/g. The mechanism of adsorption of Fe(III) metal ions in IIP-PA and NIP-PA was dominated by hydrogen bonds between the -COOH groups and Fe(III). In binary solutions, IIP-PA adsorption selectivity coefficient is higher than NIP-PA with the order of Fe(III)/Zn (II)>Fe(III)/Cu(II)>Fe(III)/Cd(II)>Fe(III)/Ag(I)

Eugenol is one of the most abundant natural resources in Indonesia. The recently bio-based polymer resin is created based on eugenol because eugenol is functionalized with the polymerizable group. In order to improve the functional properties of eugenol, in this research Eugenol–Lauryl Methacrylate copolymers (co-poly(Eg-LMA)) were synthesized by cationic polymerization using H2SO4 as an initiator under the nitrogen atmosphere. Structure identification of the copolymer showed the absorption of the vinyl group from the monomers disappear at the analysis through FTIR at the wave number 1637-1639 and 985-995 cm-1 and also 1H-NMR on the chemical shift 5,97 and 5,08 ppm. The resulting copolymers obtained brown powder in 32.03 % yieldsand melting point at 96 – 97 °C. Solubility test of the co-poly(Eg-LMA) showed that the polymer couldnot soluble in water but soluble in chloroform, diethyl ether, and benzene. Average molecular weight of co-poly(Eg-LMA) Led Ostwald viscometry was obtained 42020 with the degree of polymerization by 200.
