Continuous and batch processes of polymer enhanced ultrafiltration for the estimation of binding constants of divalent cadmium, nickel, and zinc ions have been elaborated. Polyethyleneimine was used as a complexation agent. Effect of pH and ionic strength on the binding ability of target metal ions to polyethyleneimine were estimated by continuous mode PEUF system. A mathematical model was developed to estimate apparent complexation constants of metal ions with PEI. The development of this model, which is in good agreement with experimental data, enables to compare the data obtained in both continuous and batch system and correlate the effect of pH and ionic strength with apparent binding constants.

Removal of hexavalent chromium anions via polymer enhanced ultrafiltration using a fully ionized polyelectrolyte HAKTANIR, CEREN; Ozbelge, H. Onder; Bicak, Niyazi; Yılmaz, Levent (Informa UK Limited, 2017-01-01) A fully ionized polyelectrolyte was synthesized for Cr(VI) removal from aqueous solutions by continuous polymer enhanced ultrafiltration (PEUF). Effect of operating parameters such as pH, loading, polymer, and competing ion concentrations were examined. Highest Cr(VI) retention was obtained at a loading of 0.01 at pH 4. Increasing both polymer and chromate concentrations at a fixed loading of 0.01 decreased the retention which demonstrated the effect of crowding. In the presence of competing anions such as ...
Removal of Heavy Metals from Multicomponent Metal Mixtures by Polymer Enhanced Ultrafiltration: Effects of pH, Ionic Strength and Conformational Changes in Polymer Structure Kadioglu, Sezin Islamoglu; Yılmaz, Levent; AYDOĞAN, NİHAL; Ozbelge, H. Onder (Informa UK Limited, 2010-01-01) Fractional separation of industrially important heavy metals (cadmium, nickel, zinc) from binary and ternary metal mixtures by continuous mode polymer enhanced ultrafiltration was studied. Polyethyleneimine (PEI) was used as a complexation polymer. Effects of pH and ionic strength on process efficiency were investigated. To gain insight about the characteristics of binding between highly branched PEI and metal ions and effect of salt concentration on this binding were investigated by performing dynamic and ...
Use of Specifically Tailored Chelating Polymers for Boron Removal from Aqueous Solutions by Polymer Enhanced Ultrafiltration Doganay, Ceren Oktar; Ozbelge, H. Onder; Bicak, Niyazi; AYDOĞAN, NİHAL; Yılmaz, Levent (Informa UK Limited, 2011-01-01) Two selective functional polychelatogens, namely hydroxyethylaminoglycerol functioned poly(glycidylmethacrylate (PNS) and Poly(4-Vinyl-1,3-dioxalan-2-one-co-vinyl acetate) (COP) were synthesized and utilized in polymer-enhanced ultrafiltration (PEUF) to remove boron from the aqueous solution. The effect of operating parameters on boron retention was investigated. PNS was synthesized in three molecular weights to observe the effect of molecular weight in borate retention. Increase in pH increased boron reten...
Removal of methylene blue by new tunable aryl/alkyl ionic liquids/salts (TAAILs) from aqueous solution Özdemir, Melek (Informa UK Limited, 2019-10-16) The removal of methylene blue (MB) from aqueous solution has been investigated using new tunable 1-aryl-2-alkyl-3,5-dimethylpyrazolium hexafluorophosphate salts ([Ph(R)C(R?)pz][PF6], R: -Cl, -Br, -Me, -OMe, R?: -C2H5, or -C4H9) as an extractant and methylene chloride as a diluent. The influence of p-substituent and alkyl chain length on the removal efficiency of MB from aqueous solution was investigated. The obtained results show that MB was extracted from aqueous solution with high extraction efficiency up...
Effect of operating parameters on the separation of sugars by nanofiltration Aydogan, N; Gurkan, T; Yılmaz, Levent (Informa UK Limited, 1998-01-01) Due to the complexity of fermentation mixtures, separation of solutes and secondary substrates has a special importance. Membrane processes such as nanofiltration may offer good alternatives for the separation of fermentation products or recovery of substrates. For an efficient separation, the membrane type and operating parameters such as feed flow rate, operating pressure, and feed should be optimized. In this study the separation and recovery of sugars were targeted. It was found that with an increase of...
