“…The emulsion breakage is defined as the ratio of the internal phase volume leaked into the external phase and is calculated by the mass balance as Eqs. 3 and 4 68, 69:

true ζ = (\frac{V_{S}}{V_{I}}) \times 100

true V_{normalS} = V_{normalE} (\frac{10^{- p H_{0}} - 10^{- pH}}{10^{- pH} - C_{H^{+}}^{int}})

Pertraction of Vanadium(V) from Dilute Acidic Media by an Emulsion Liquid Membrane Containing a Commercial Extractant

2022

View full text Add to dashboard Cite

Emulsion liquid membrane (ELM) pertraction of VV ions from dilute acidic solution by using a mixture of di(2‐ethylhexyl)phosphoric acid (D2EHPA) and mono(2‐ethylhexyl)phosphoric acid (M2EHPA) was studied. First, solvent extraction of VV from an aqueous medium was performed, and the optimum feed pH and extractant concentration were obtained. Tributyl phosphate was used as modifier to increase membrane stability and decrease membrane swelling. The effects of diluent type, extractant concentration of the emulsifier concentration, stripping reagent concentration (sulfuric acid), organic phase/stripping phase volume ratio, emulsification time and speed, feed initial pH, agitation speed, temperature, and contact time on VV extraction efficiency and ELM stability were considered.

“…ELM is a single-step process that applied a liquid-liquid extraction principle where the extraction and stripping occurred concurrently in order to concentrate and purify the desired solute [20]. Pharmaceutical pollutants such as ethyl-paraben (20 ppm) [21], diclofenac (60 ppm) [22], amoxicillin (71 ppm) [23] and tetracycline (100 ppm) [24] could be successfully extracted using different formulations of ELM. It was reported by Razo-Lazcano et al that Pharmaceutical pollutants such as ethyl-paraben (20 ppm) [21], diclofenac (60 ppm) [22], amoxicillin (71 ppm) [23] and tetracycline (100 ppm) [24] could be successfully extracted using different formulations of ELM.…”

Removal of Ibuprofen at Low Concentration Using a Newly Formulated Emulsion Liquid Membrane

et al. 2021

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.

“…Most PPCPs reach the water bodies due to the failure of the conventional wastewater treatment plants (WWTPs) to completely remove them ( Hijosa-Valsero et al., 2010 ). Treatment processes, such as adsorption ( Bunmahotama et al., 2020 ; Fu et al., 2019 ; Mohammed and Kareem, 2019 ; Mohammed et al., 2020 ), membrane separation ( Liu et al., 2018 ; Xu et al., 2019 , 2020 ), emulsion liquid membrane ( Mohammed et al., 2020a , 2020b ) and advanced oxidation processes ( Lin et al., 2016 ; Yang et al., 2016 ) do not provide a complete solution to the problem due to the emergence of secondary pollution represented by the concentrated phase of the pollutant. Moreover, such technologies are not feasible in the case of low pollutants concentrations ( Rodriguez-Narvaez et al., 2017 ).…”
