Selective separation of cobalt and nickel by flat sheet supported liquid membrane using Alamine 300 as carrier

Facilitated transport of phenol through supported liquid membrane containing bis(2-ethylhexyl) sulfoxide (BESO) as the carrier

“…The effect of stirring speed in the feed and stripping phases was studied to optimize uniform mixing and minimize the thickness of the aqueous boundary layer for an effective PhOH permeation [32]. Thus, the stirring of the source and receiving phases was carried out from 400 to 1300 rpm and the results are depicted in Fig.…”

Preparation of new polysulfone capsules containing Cyanex 272 and their properties for Co(II) removal from aqueous solution

“…Up to now, the various techniques, such as adsorption [2][3][4][5][6][7], facilitated transport through bulk liquid membrane [8], supported liquid membrane [9,10], emulsion liquid membrane [11,12] and liquid-liquid extraction (LLE) [13,14] have been used for recovery or removal of Co(II) from aqueous solutions.…”

Supported Liquid Membrane Principle and Its Practices: A Short Review

“…is thin layer of organic phase can be immobilized onto a suitable inert microporous support, which when interposed in between two aqueous solutions is termed supported liquid membrane (SLM). In this three-phase extraction technique and analytes are extracted from a continuously �owing aqueous sample through an organic liquid phase into another usually temporally stagnant, aqueous phase [12][13][14][15][16][19][20][21][22][23][24][25][26].…”

“…e most signi�cance feature of the reaction is the degree of the extraction of the respective extractant at a particular concentration. e extractants used for extraction by compound formation may be chelating such as LIX 84-I, LIX 64N, LIX 62N, LIX 860, and so forth, or may be acidic such as D2EHPA, PC88A, Cyanex 272 (phosphoric acid derivatives), and so forth, [14][15][16][19][20][21][22]. ese extractants are quite familiar in the hydrometallurgical process for the extraction/separation of various metal ions that is, Cu, Zn, Co, Ni, Fe, Mn, Mo (VI), and so forth from the leach liquor (obtained from primary/secondary resources) [7,8,15,16,27].…”
