Ultrafiltration of Divalent Metal Cations from Aqueous Solution Using Polycarboxylic Acid Type Biosurfactant

Treatment of concentrated arsenic(V) solutions by micellar enhanced ultrafiltration with high molecular weight cut-off membrane

“…The improvement of surfactant rejection can be then approached by the modification of membrane module or material in order to reduce the concentration polarisation [12]. Nevertheless concentration polarisation itself can be also exploited to design MEUF working below CMC and reducing surfactant release and consumption.…”

Adsorption of Pb2+, Zn2+, and Cd2+ from waters by amorphous titanium phosphate

“…Accordingly, various technologies, including chemical precipitation [2], adsorption [3], membrane processes [4], electrolytic methods [5], and ion exchange [6][7][8][9], have been proposed for their remediation from waste streams. Ion exchange is one of the most frequently studied and widely applied techniques for the treatment of metal-contaminated wastewater [6,7], and polymeric cation or anion exchangers are always employed for this specific purpose [6,7].…”

Effect of valences on removal of anionic pollutants using micellar-enhanced ultrafiltration

“…Few researchers have focused on the multi-pollutants system [13,14,[19][20][21][22][23], which is the real field condition. Even most of them tried to remove mixtures of heavy metals with the same valences (divalent) that determined the performance of MEUF [16,[19][20][21][22][23]. In multi-system, the removal of ions with a smaller valence may be inhibited by the presence of ions with a higher valence.…”

“…Many researchers have studied the application of MEUF for the separation of various ionic pollutants including heavy metals, nitrate, chromate, and phosphate [13][14][15][16][17][18][19][20][21][22][23]. Few researchers have focused on the multi-pollutants system [13,14,[19][20][21][22][23], which is the real field condition.…”

“…Micellar-enhanced ultrafiltration (MEUF) has been used for the ionic pollutants from aqueous streams [13][14][15][16][17][18][19][20][21][22][23]. It combines the high rejection of reverse osmosis with the higher flow rate of ultra filtration.…”
