The fibers supported liquid membrane was impregnated with different concentrations carrier. The experimental variables explored were concentration of yttrium (III) ions, pH of source phase, PC-88A concentration in membrane phase, acid concentration in receiving phase and stirring speed. The pre-concentration of yttrium MO ions was investigated from the dilute solutions. The two-channel fibers supported liquid membrane solvent extraction was investigated for the transport of yttrium (III) ions from the source to membrane and membrane to receiving phase.

The fibers supported solid membranes were prepared with chemical synthesis from cellulose fibers and citric acid with the carboxylic acid ion exchange groups introduced. The experimental variables, such as concentration of metal ions (10(-2) to 10(-4) mol.L(-1)) in the source solution, mixed solvent composition [for example, acetylacetone, (2,4-pentanedione), (HAA) 20% (by volume), 1,4-dioxane 10% to 60% and HCl 0.25 to 2 mol.L(-1)] in the receiving phase and stirring speed (50-130 r.min(-1)) of the bulk source and receiving phase, were explored. The efficiency of mixed solvents for the transport of metal ions from the source to receiving phase through the fiber supported solid membrane was evaluated. The combined ion exchange solvent extraction (CIESE) was observed effective for the selective transport of thallium, indium and gallium metal ions through fiber supported solid membrane in mixed solvents. The oxonium salt formation in the receiving phase enhances thallium, indium and gallium metal ion transport through solid membrane phase. The selective transport of thallium metal ions from source phase was observed from indium and gallium metal ions in the presence of hydrochloric acid in organic solvents in receiving phase. The separation of thallium metal ions from the binary mixtures of Be(II), Ti(IV), Al(III), Ca(II), Mg(II), K (I), La(III) and Y(III) was carried out in the mixed solvent system using cellulose fiber supported solid membrane.</p>10aacetylacetone10aextraction10afiber supported solid membrane10ametal ions transfer10astripping1 aGaikwad, Abaji, G.  uhttps://library.ncl.res.in/content/transport-indium-gallium-and-thallium-metal-ions-through-chromatographic-fiber-supported-001867nas a2200229   4500008004100000022001400041245012700055210006900182260010900251300001200360490000700372520094000379653003701319653001101356653001501367653003501382653001701417653003601434653001401470100002301484856013001507       2011                        eng d  a0352-956800aTransport of metal ions through cellulose fiber supported solid membrane into tributyl phosphate containing mixed solvents0 aTransport of metal ions through cellulose fiber supported solid   aBERISLAVICEVA 6, PO BOX 123, HR-10000 ZAGREB, CROATIAbCROATIAN SOC CHEMICAL ENGINEERING TECHNOLOGYcDEC  a425-4310 v253 a<p>A novel cation exchange fiber supported solid membrane was developed for transport of cobalt, manganese and nickel metal ions.
