“…This breakage therefore reduce succinic acid extraction at high treat ratio. This results is in line with Sulaiman et al [11], who reported emulsion breakage occur at high treat ratio. Further reducing the treat ratio to 1:5 reduce the succinic acid extraction performance because of the reduction in the dispersibility of the emulsion.…”

“…This is because increasing the homogenizer speed produce higher number of droplets with greater interfacial area, thus stabilize the emulsion. A study by Sulaiman et al [11] also found that higher homogenizer speed increase emulsion stability. Further increase the speed to 9000 shows that the stability is lower than that of 7000 rpm.…”

Emulsion Liquid Membrane (ELM) process have shown a great potential in wide application of industrial separations such as in removal of many chemicals, organic compounds, metal ions, pollutants and biomolecules. This system promote many advantages including simple operation, high selectivity, low energy requirement, and single stage extraction and stripping process. One potential application of ELM is in the purification of succinic acid from fermentation broth. This study outline steps for developing emulsion liquid membrane process in purification of succinic acid. The steps include liquid membrane formulation, ELM stability and ELM extraction of succinic acid. Several carrier, diluent and stripping agent was screened to find appropriate membrane formulation. After that, ELM stability was investigated to enhance the recovery of succinic acid. Finally, the performance of ELM was evaluated in the extraction process. Results show that formulated liquid membrane using Amberlite LA2 as carrier, palm oil as diluent and sodium carbonate, Na 2 CO 3 as stripping agent provide good performance in purification. On the other hand, the prepared emulsion was observed to be stable up to 1 hour and sufficient for extraction process. In conclusion, ELM has high potential to purify succinic acid from fermentation broth.Keywords: emulsion liquid membrane, purification, succinic acid, formulation, stability Abstrak Proses emulsi membran cecair (ELM) telah menunjukkan potensi yang hebat dalam pelbagai aplikasi pemisahan perindustrian seperti pembuangan pelbagai bahan kimia, sebatian organik, ion logam, bahan pencemar, dan molekul biologi. Sistem ini menawarkan banyak kelebihan termasuk operasi yang mudah, sangat selektif, keperluan tenaga yang rendah, dan proses pengekstrakan dan pelucutan dalam satu peringkat. Satu potensi aplikasi ELM adalah dalam proses penulenan asid succinic daripada larutan penapaian. Kajian ini menggariskan beberapa langkah untuk membangunkan proses emulsi membran cecair dalam penulenan asid sussinik. Langkah -langkah tersebut termasuklah formulasi cecair membran, kestabilan ELM, dan pengekstrakan asik sussinik menggunakan ELM. Beberapa pembawa, pelarut, dan agen pelucutan telah ditapis untuk mencari rumusan membran yang sesuai. Selepas itu, kestabilan ELM dikaji untuk meningkatkan perolehan asid sussinik. Akhir sekali, prestasi ELM dinilai dalam proses pengekstakan. Keputusan menunjukkan bahawa rumusan cecair membran menggunakan Amberlite LA2 sebagai pembawa, minyak kelapa sawit sebagai pelarut dan natrium karbonat, Na 2 CO 3 sebagai agen pelucutan memberikan prestasi yang baik dalam proses penulenan. Disamping itu, emulsi diperhatikan stabil sehingga 1 jam dan ini mencukupi untuk proses pengekstrakan. Kesimpulannya, ELM berpotensi tinggi untuk mnulenkan asid sussinik daripada proses penapaian.Kata kunci: emulsi membran cecair, penulenan, asid sussinik, formulasi, kestabilan

“…These approaches were invented by Li about 40 years ago [11]. The potential applications of ELM include extraction of fermentation products, hydrocarbon fraction, wastewater treatment, organic compounds elimination such as phenol and aniline, biochemical processes, metallic ions recovery, penicillin G extraction, and lignosulfonates [12][13][14][15][16][17][18][19][20][21]. ELM is a promising and valuable method that offers several advantages such as ease of operation, large mass transfer area that leads to fast extraction and stripping, capable of applying carrier-mediated transport, low energy consumption, high efficiency, and high selectivity [22].…”

A B S T R A C TKraft lignin (KL) represents a key sustainable source of biomass for transformation into biofuels and high-value specialty chemicals. Excess lignin in pulping wastewater creates pollution problems, hence affecting human. Thus, the KL recovery from pulping wastewater by emulsion liquid membrane was investigated and optimized using response surface methodology in this study. The liquid membrane was prepared by dissolving carrier tricaprylylmethylammonium chloride (Aliquat 336) and hydrophobic surfactant sorbitan monooleate (Span 80) in kerosene (diluent) with sodium bicarbonate (NaHCO 3 ) as the internal stripping phase and 2-ethyl-1-hexanol as the modifier. The comparison between the experimentally optimized, and the RSM optimized values was accomplished by optimizing the following parameters: carrier and stripping agent concentration and treat ratio of emulsion to feed phase. The maximum KL recovery of 97% was obtained under the optimum condition at 0.012 M of Aliquat 336, 0.32 M of NaHCO 3 , and 1:4.8 of treat ratio.
