Telah dilakukan penelitian tentang studi transpor fenol melewati membran cair polieugenol. Studi transpor fenol ini menggunakan pipa U yang berisi membran cair untuk memisahkan fasa sumber dan fasa pelucut. Beberapa faktor yang mempengaruhi transpor menggunakan membran cair polieugenol diantaranya pH fasa sumber, waktu transpor, konsentrasi fasa pelucut, dan konsentrasi membran cair polieugenol. Setiap variasi menggunakan 10 mL larutan fenol 60 ppm, 5 mL membran cair polieugenol dan 10 mL larutan NaOH. Konsentrasi fenol setelah transpor pada fasa sumber dan fasa pelucut ditentukan dengan menggunakan reagen 4-aminoantipirin dalam suasana larutan kalium ferri sianida kemudian warna antipirin yang terbentuk diekstraksi menggunakan kloroform lalu absorbansinya diukur menggunakan Spektrofotometer UV-Vis pada λ 455 nm. Hasil penelitian menunjukkan bahwa membran cair polieugenol dapat mentranspor fenol optimum pada pH fasa sumber 6,5 dengan waktu transpor selama 72 jam, konsentrasi NaOH 1,0 M dan konsentrasi membran cair polieugenol 1,5×10-3 M, yang memberikan hasil % transpor sebesar 71,6%. Hasil FT-IR menunjukkan adanya interaksi fenol-polieugenol, yang ditunjukkan dengan perbedaan pola serapan antara fenol, polieugenol dan fenol-polieugenol.

It has been researhed, the study of phenol transport through liquid membrane of polyeugenol. It used a U-shape tube which contained liquid membrane to separate the source phase and receiving phase. Some factors that affected the phenol transport were pH of source phase, transport duration, carrier concentration in the membrane phase, and basicity of the receiving phase. Each variation using 10 mL of 60 ppm phenol solution, 5 mL of liquid membrane polieugenol and 10 mL of NaOH solution. The concentration of phenol after the transport process was determined using the reagent of 4-aminoantipyrine in a solution of potassium ferricyanide, the color of antipyrine formed was extracted using chloroform and then its absorbance was measured using UV-Vis spectrophotometer at λ 455 nm. The results of this researh showed that the liquid membrane of polyeugenol could transport the phenolic solution optimum on source phase at pH 6.5 and transport duration 72 hours, NaOH concentration 1.0 M and concentration of polyeugenol liquid membrane 1.5×10-3 M, which gave yield of transport 71.6%. FT-IR analysis showed that the interaction of phenolpolyeugenol, which was indicated by the difference in uptake pattern between the phenol, polyeugenol and phenol-polyeugenol.
