Abstract
The aim of this study is to develop a stable emulsion liquid membrane for acetaminophen removal through membrane breakage. In this work, Trioctylamine (TOA), Span 80 and kerosene were used as carrier, surfactant and diluent, respectively in membrane phase while ammonia solution was used as a stripping agent in the internal phase. Research was conducted on various parameters such as stripping agent concentration, agitation speed, extraction time and treat ratio. The stripping agent concentration was varied from 0.05 M to 0.2 M while agitation speed was investigated at 200 rpm to 500 rpm. The best condition achieved for acetaminophen removal from aqueous solution via emulsion liquid membrane were at 0.1M of stripping agent using 300 rpm agitation speed for 3 minutes of extraction time with a treat ratio of 3:1. Investigation on membrane breakage revealed the lowest membrane breakage achieved was 0.17%.
