Facilitated transport of cationic dyes through a supported liquid membrane with D2EHPA as carrier

Extraction of anionic dye from aqueous solutions by emulsion liquid membrane

“…Recently, there has been increasing interest in the application of liquid membrane processes as attractive alternative treatments for the removal of dyes in wastewater [1][2][3][4][5][6]. In the emulsion liquid membrane (ELM) process, both extraction and stripping steps are combined in one stage, which leads to simultaneous purification and concentration of the solute.…”

Selective Extraction of Cadmium from Multicomponent Acidic Leach Solutions by Emulsion Liquid Membrane using Amberlite LA-2 as Extractant

“…Therefore, emulsion liquid membrane systems have now become an alternative separation technique for metals from dilute solutions as they offer advantages over conventional solvent extraction such as the use of minimal amounts of solvent and low capital cost (20,21). Particularly, an ELM process has sufficient ability to selectively separate metals from aqueous solutions using a double W=O=W emulsion stabilized by the use of suitable surfactants, with a reduced amount of organic solvent and greater extraction.…”

Gas permeation behavior of CTA polymer inclusion membrane (PIM) containing an acidic carrier for metal recovery (DEHPA)

“…It is also used in complexation reactions for several organics such as amino acids, polyamines and cationic dyes [36][37][38][39][40][41].…”
