Study on Phenol Compound Transport using Polieugenol Liquid Membrane with Dichloromrthane Solven
        Phenol is a component in waste water that is very dangerous, because it is toxic, corosif on skins and carcinogenics. It can be separated by using liquid membranes. Membrane can be a very specific filter. Liquid membrans transport technique used three phase. The phase are donor phase that contain substance to be separated, membrane phase that contains ligan in the organic solvents, and aceptore phase that contain base as release agent of ligans complex. Polyeugenol have a condition as a ligan that is capable as selective chelate agent for phenol coumpounds. In this research, polieugenol were used with dichloromethane solvents as a membrane for separating and transporting phenol separated, NaOH as release phase with variating pHs, concentrations of release phase, transport time and membrane concentrations. The result showed that liquid membrane of polieugenol in dichloromethane solvent can transport phenol at source phase pH 6.5, at optimum released concentration was 0.75 M, optimum transport times was 72 hours, and optimum membran concentrations was 1,5×10-3 with % transport was 65.2%.

ABSTRAK
       Fenol merupakan salah satu komponen dalam air limbah yang sangat berbahaya, karena beracun dan bersifat korosif terhadap kulit serta karsinogenik. Fenol dapat dipisahkan dengan menggunakan  membran cair. Membran dapat bertindak sebagai filter yang sangat spesifik. Teknik transpor membran cair melibatkan tiga fasa yaitu fasa donor, mengandung bahan yang akan dipisahkan, fasa membran berisi ligan dalam pelarut organik dan fasa akseptor yang berisi basa sebagai agen pelepas dari kompleks ligan.Polieugenol mempunyai syarat sebagai ligan sehingga mampu berfungsi sebagai agen pengkhelat yang selektif untuk senyawa fenol. Pada penelitian ini digunakan polieugenol dengan pelarut diklorometana sebagai membran untuk pemisahan dan transpor senyawa fenol, dan  NaOH sebagai fasa pelucut dengan memvariasikan pH, konsentrasi fasa pelucut, waktu transpor dan konsentrasi membran. Hasil penelitian menunjukan bahwa membran cair polieugenol dalam pelarut diklorometana dapat mentranspor fenol pada pH fasa sumber optimum 6,5, pada konsentrasi pelucut optimum 0,75 M, waktu transpor optimum 72 jam, dan pada konsentrasi membran optimum 1,5×10-3 dengan % transpor 65,2%.
