A new emulsion liquid membrane was prepared for dysprosium (Dy) extraction from aqueous solution using multi-walled carbon nanotubes (MWCNTs). The influence of MWCNT concentration, carrier and surfactant concentration, stirring speed, feed-phase pH, and internal phase concentration and their interactive effects were studied. A regression model for Dy extraction was developed and the parameters were optimized by response surface methodology. The extent of extraction increases with higher MWCNT concentration up to a certain level. The Dy extraction through the liquid membrane containing MWCNT improves with time. Moreover, the overall mass transfer coefficient was enhanced in the presence of MWCNT due to the formation of a more stable emulsion and liquid membrane.

“…Liquid membrane technology has attracted much interest for its potential impact in the fields of separation processes because the main advantage of liquid membrane configuration treatment is a single step process, in which removal and recovery processes occur simultaneously [6,7]. This technique also provides high efficiency in separation and selectivity toward the desired solute as reported by Harrudin et al [8].…”

The presence of chromium in the natural water can be toxic to aquatic organism and is one of the major environmental problems. Therefore, the removal and recovery of chromium from industrial wastewater is very crucial to accomplish the standard discharge concentration limit. Supported liquid membrane is one of the processes which combines the extraction and recovery process in one single stage. This paper presents an experimental study on the removal and recovery of chromium ions from acidic aqueous solutions through a flat-sheet supported liquid membrane (FSSLM) system. Through this system, chromium ions were transported from feed phase into stripping phase via Tri-n-octyl-methylammoniumchloride (TOMAC)-kerosenepolypropylene supported liquid membrane (SLM). The liquid membrane phase was prepared by dissolving the corresponding volume of the carrier, TOMAC in organic diluent of kerosene. The stripping agent used was sodium hydroxide (NaOH) solution whereas the membrane support used was commercial Accurel polypropylene membrane with good features of 100 µm thickness, porosity of 72% and effective pore size of 0.10 µm. The chromium ion concentration in the feed and stripping phases as a function of time was analysed using an atomic absorption spectrometry (AAS). The effects of different operational variables such as TOMAC concentration in the membrane phase, NaOH concentration in the stripping phase and pH of the aqueous feed phase were investigated. The result demonstrated that about 90 and 98% of 150 ppm of chromium was removed and recovered, respectively at favorable condition of 1.0 M TOMAC, 0.5 M NaOH and pH 2 of the feed phase.Keywords: supported liquid membrane, chromium, removal, recovery, acidic aqueous solution Abstrak Kehadiran kromium di dalam sumber air semula jadi adalah toksik kepada organisma akuatik dan salah satu masalah utama alam sekitar.

The extraction of amoxicillin (AMX) from aqueous solutions by emulsion liquid membranes (ELMs) was investigated for the first time. The liquid membrane phase of the ELM consisted of Aliquat 336 as carrier, Span 80 as surfactant, n‐hexane as diluent, and sodium chloride solution as internal phase. Response surface methodology (RSM) based on central composite design (CCD) was applied to evaluate and optimize the effects of several parameters such as carrier concentration, feed concentration, internal phase concentration, and treat ratio (volume ratio of the external phase to the emulsion phase). A polynomial model was fitted to predict the extraction yield of AMX. Under optimized conditions, the highest extraction yield of AMX was 99.8 %.
