Predispersed solvent extraction of negatively complexed copper from water using colloidal liquid aphron containing a quaternary ammonium salt

Copper ion removal from dilute solutions using colloidal liquid aphrons

“…They show a significant resistance to coagulation and can be stored for long periods of time without any noticeable coalescence, and can also be transported by pumping without destroying the structure [42,43]. These properties make CLAs of interest for separation processes such as removal of metals [44,45]; extraction of antibiotics [46] and organic pollutants [47,48]; oil recovery [39,42]; and water remediation [49]. For a recent review of aphron research, please see Molaei and Waters (2015) [50].…”

Continuous predispersed solvent extraction process for the downstream separation of 2,3-butanediol from fermentation broth

“…Previous investigations reported in literature on CLAs include the screening of surfactant types and concentration for CLA formation and its influence on CLA stability [24][25][26]. The application of CLAs in PDSE is reported for compounds such as metals, antibiotics, antioxidants, organic dyes, and organic acids [27][28][29][30][31][32][33][34]. Only very few studies on mechanism of CLA mass transfer are investigated in the literature [35,36].…”

Selective removal of copper and nickel ions from synthetic process water using predispersed solvent extraction

“…PDSE showed many potential applications such as the extraction of antibiotics and organic pollutants, separation of bio‐based products, removal of metals, oil recovery, and water remediation . PDSE was first employed in 1980s by Sebba, in order to extract organic solutes from water, and further studies revealed the higher efficiency of PDSE compared to conventional solvent extraction .…”
