“…Because it has a broad separation spectrum, is selective, and is simple to use, liquid membranebased separation technology is presently generating an increasing amount of interest (Rosly et al 2018). These benefits result from the fact that liquid membrane separation doesn't require any extra chemical substances and that it uses very little energy and is therefore technically, economically, and energetically advantageous (Pavón et al 2020;Kazemi et al 2014).…”

In this research, Polymer Inclusion Membrane (PIM) was created using copoly-eugenol ethylene glycol dimethacrylate (co-EEGDMA) 10% as a carrier, dibenzyl ether (DBE) as a plasticizer, and polyvinyl chloride (PVC) as the base polymer. Following that, the membrane was used in phenol transport experiments under a variety of circumstances, including pH of the phenol in the source phase, NaOH concentrations in the receiving phase, and transport times. The ability and stability of the membrane were also evaluated under several influencing parameters such as plasticizer concentration, salt concentration, and PIM membrane age (lifetime). Phenol concentration was analyzed using UV-Vis spectrophotometer, and PIM membrane was characterized before and after use using Fouriertransform infrared spectroscopy (FT-IR). According to the testing findings, phenol had an ideal pH of 5.5 in the source phase and a concentration of 34.07% in the receiving phase. Additionally, it was discovered that the ideal NaOH content in the receiving phase was 0.5 M with a phenol concentration of 58.24%. The experiments with varied transport times demonstrated that the optimum time was 48 hours with the phenol concentration of 90.82% in the receiving phase. The results of UV-Vis spectrophotometry analysis demonstrated that phenol transportation of 91.54% was achieved with the use of 0.3132 g plasticizer. Under ideal circumstances of pH 5.5 of phenol solution in the source phase, 0.5 M NaOH concentration, and phenol transport time of 48 hours, a membrane prepared from PVC as a base polymer, 10% co-EEGDMA as a carrier, and DBE as a plasticizer can be used to transport phenol. The membrane's stability was only 24 days when no NaNO 3 salt was added, but it grew to 108 days when 0.01 M NaNO 3 salt was added.

“…Conversely, the common use of stripping agents such as HCl, Na 2 CO 3 , H 2 SO 4 , HNO 3 and NH 3 in the internal phase may have contributed to the pollutant removal efficiency. By using HCl, Na 2 CO 3 and H 2 SO 4 in the formulation, for example, the percentage of phenol removed was less than 40% [26]. The formulation of ELM using NH 3 (internal phase), TOA (carrier) and kerosene (membrane phase) was reported to achieve 80% removal of acetaminophen (antibiotics) from feed phase [18].…”

Ibuprofen (IBP) is a pharmaceutical product that is widely prescribed as an over-the-counter painkiller. It has been classified as a contaminant of emerging concern (CEC) that has received global attention in the search for a better wastewater separation technology. The emulsion liquid membrane (ELM) is one of the potential solutions for IBP removal from wastewater owing to its advantages, such as the ability to remove a highly soluble solute, energy efficient and tuneable formulation. To develop this ELM, a series of parameters such as stirring speed, emulsification time, organic to internal phase volume ratio (O/I), internal phase concentration, carrier concentration and surfactant concentration were studied. The extraction was carried out for 15 min stirring time and the concentration of IBP in the feed phase was determined using a UV-Vis spectrophotometer. The optimum formulation for the ELM was found at 300 rpm stirring speed, 20 min emulsification time, 3:1 of O/I, 0.1 M ammonia, NH3 (stripping agent), 6 wt% trioctylamine, TOA (carrier) and 2 wt% sorbitan monooleate, Span 80 (non-ionic surfactant). IBP removal of 89% was achieved at the optimum parameters of ELM. The current research demonstrated that a newly formulated ELM has great potential in removing a low concentration IBP from wastewater.
