Abstract    A study on the extraction of Acetaminophen (ACTP) which is also known as paracetamol, from aqueous solution by emulsion liquid membrane process using Taylor-Couette Column (TCC) was investigated. An ELM consists of three phase system which are the external, membrane and internal phases. The external phase containing the ACTP aqueous solution to be treated. Basically, the internal and membrane phase form the primary water-in-oil (W/O) emulsion using ultrasonic probe which is to be dispersed in the external phase. In this work, Trioctylamine (TOA), Span 80 and kerosene were used as carrier, surfactant and diluent, respectively in membrane phase. Meanwhile ammonia solution was used as a stripping agent in the internal phase. The influence of several operating conditions such as surfactant and carrier concentration, ultrasonic power, emulsification time, treat ratio, stirring time and stirring speed were investigated. The results showed that the present work proved that the ELM using TCC system was capable to effectively remove about 85 % ACTP from aqueous solutions under optimum conditions of 15 minutes of emulsification time, 6 wt.% of Trioctylamine and Span 80, 20 W power of ultrasonic probe, 5 minutes of extraction time, frequency angular ratio of 1.0 and treat ratio of 3:1.

یک مطالعه بر روی استخراج استامینوفن (ACTP) که همچنین به عنوان پاراستامول شناخته شده است، از محلول آبی با روش غشای مایع امولسیون(ELM) با استفاده از ستون تیلور کویت (TCC) مورد بررسی قرار گرفت. یکELMمتشکل از سیستم سه فازی است که از فاز خارجی، غشا و فاز داخلی تشکیل شده است. فاز خارجی حاوی محلول آبی ACTPاست که می بایست مورد درمان و جداسازی فرارگیرد. اساسا فاز داخلی و غشایی، امولسیون اولیه آب در روغن (W / O)است که با استفاده از پروب اولتراسونیک که در فاز خارجی پراکنده می شود، تشکیل می شود. در این کار، تری اکتیل آمین (TOA)، Span 80 و نفت سفید به عنوان حامل، سورفاکتانت و رقیق کننده به ترتیب در فاز غشاء مورد استفاده قرار گرفتند. در عین حال محلول آمونیاک به عنوان یک عامل پاک کننده و تمیزکننده در فاز داخلی استفاده شد. تأثیر چندین شرایط عملیاتی مانند سورفاکتانت و غلظت حامل ، قدرت اولتراسونیک، زمان امولسیون، نسبت درمان و جداسازی، زمان جداسازی و سرعت همزدن جهت جداسازی مورد بررسی قرار گرفت. نتایج نشان می دهد که سیستم ELM با بهره گیری از سیستم TCC توانایی حذف حدود 85٪ ACTP از محلول های آبی را در شرایط بهینه 15 دقیقه زمان امولسیون، 6٪ وزنی تری اکتیل آمین و Span 80، قدرت پروب اولتراسونیک20 W ،و 5 دقیقه زمان استخراج با نسبت زاویه ای فرکانس 1.0 و نسبت ریکاوری 3: 1 بهترین شرایط برای جداسازی می باشد.
