Selective extraction of cobalt ions through polymer inclusion membrane containing Aliquat 336 as a carrier

Osman TUTKUN

This study reports the selective separation of Co (II) from mixtures of cobalt and nickel solutions using cellulose tri-acetate (CTA)-based polymer inclusion membranes, which incorporated the commercial extractant trioctylmethylammonium chloride (Aliquat 336). Tributylphosphate (TBP) was used as a modifier, and 2- nitro phenyl pentyl ether (2-NPPE) was applied as the plasticiser to prepare the membranes. Several important transport parameters such as the plasticiser concentration, carrier type, carrier concentration, pH of acid, stirring speed, stripping solution type and concentration, comple ...Более

Characterization of polymer inclusion membrane containing Aliquat 336 as a carrier

Osman TUTKUN

The presented research is about characterization of Cellulose Triacetate (CTA) based Polymer Inclusion Membranes (PIMs) which incorporated the commercial extractant Aliquat 336, Tributylphosphate (TBP) as modifier and 2-Nitro Phenyl Pentyl Ether (NPPE) as plasticizer, for the preparation of the membranes. Chemical and physical characteristics of the synthesized membranes especially membrane thickness and side difference effects were investigated. Different surface structures and membrane thickness affect the extraction efficiency of membranes. Membrane extraction experiments were studied where ...Более

Selective separation of gallium from various ions by polymer inclusion membranes based on CTA/PVC blend using TOPO as carrier

Osman TUTKUN | Kurmancan KAPAROVA

Selective transport of gallium from HCl media containing other ions such as Zn, Co, and Ni, by polymer inclusion membranes (PIM), based on CTA/PVC blend using trioctylphosphine oxide (TOPO) as carrier and 2-nitrophenylpentyl ether (2-NPPE) as plasticizer is studied. The effect of various parameters such as the HCl concenration in the feed, HCl concenration in the stripping phase, carrier (TOPO) concentration, 2-NPPE concentration, the cellulose triacetate (CTA)/poly(vinyl chloride) (PVC) as the polymer-blend was experimentally studied and the optimum conditions were determined. It was possible ...Более

Separation of chromium and nickel ions by supported liquid membranes using TOA as carrier

Osman TUTKUN | Kurmancan KAPAROVA

The extensive use of chromium in leather tanning, metallurgy, electroplating and other industries has resulted in the release of aqueous chromium to the subsurface at numerous sites. Cr (VI) has received considerable attention owing to its extensive industrial applications and has long been recognised as a toxic substance due to its strong oxidising potential and the ease with which it can cross the biological membranes. In recent years the application of various solvent extraction technologies to the removal and concentration of chromium have been widely studied; chemical precipitation, ion e ...Более
