Study of transport of phenol using the surfactant SDS (Sodium Dodecyl Sulfate), Tween-80 as additive in the source phase and oleic acid, Span-60 additive in the membrane phase with bulk liquid membrane techniques has been performed. Transportation system was in one way using solution of phenol 2.13 x 10 -4 M as the source phase, 30 mL of chloroform as membrane phase, a solution of 12 mL of 0.1 M NaOH as the receiving phase and stirring speed of 340 rpm. The concentration of phenol that transported into receiving phase and remaining in the source is determined by measuring phenol method using 4-aminoantipirin and monitored with a spectrophotometer. The result showed the percentage of transport of phenol into the receiving phase is 93.07% within 120 minutes without any additive surfactant, while for additive oleic acid and Span-60 the percentage of transport phenol is 97.28% and 88.84% within 90 minutes. Phenol transport system analyzed by means of a kinetic model involving consecutive irreversible firstorder reaction with the constants exraction of phenol from the source to the membrane (k1) of 0.0346 minute Fenol dan turunannya merupakan senyawa kimia bahan baku industri obat yang termasuk golongan beracun dan berbahaya. Paraaminofenol adalah salah satu senyawa turunan fenol yang merupakan bahan baku obat paracetamol dan obat lainnya. Toksisitas fenol, aniline dan turunan fenol limit batasnya 50 ppb dalam air minim dan air laut [1] . Oleh karena itu, kadar fenol dan senyawa turunannya di perairan dan dalam air limbah industri obat yang akan di buang ke perairan harus dikontrol.Studi untuk menghilangkan dan mengotrol kadar fenol dan turunannya dari air limbah telah banyak dirancang. Penelitian yang telah dilakukan untuk pengolahan air limbah senyawa para-aminofenol adalah dengan lumpur granular pada suhu 30 o C, pengadukan selama 150 hari. Uji biodegradabilitas dilakukan dengan mengukur komposisi hasil gas metananya. Ditemukan bahwa bakteri metanogen dapat menyelesaikan mineralisasi senyawa para-aminofenol [1,2] . Metode klisik untuk pemisahan selektif senyawa organik seperti destilasi, fraksionasi, ekstraksi pelarut, dan lain-lain, membutuhkan biaya yang cukup besar.Membran cair dapat digunakan sebagai alternatif untuk metode pemisahan karena cukup ekonomis, sensitifitas tinggi, dan 150
