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 to 99.7 % in a very short time. The salt (4a) used for extraction of MB was recovered and reused for four runs.

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 ...
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 phenolic compounds from rubber-textile wastewaters by physico-chemical methods Ozbelge, TA; Ozbelge, OH; Baskaya, SZ (Elsevier BV, 2002-09-01) Removal of phenolic compounds from rubber-textile wastewaters (RTWWs) by physico-chemical process was investigated by using four different types of coagulants (Al-2(SO4)(3), Fe-2(SO4)(3), FeSO4, FeCl3) with or without lime (Ca(OH)(2)) addition, in jar-test experiments. The RTWWs of the present tire-cord fabric plant may contain seven different types of dipping solutions (DSs), which provide an adhesive property to the fabric. The optimum results were obtained by using 50% FeCl3 solution and lime at various ...
Estimation of Binding Constants of Cd(II), Ni(II) and Zn(II) with Polyethyleneimine (PEI) by Polymer Enhanced Ultrafiltration (PEUF) Technique Kadioglu, Sezin Islamoglu; Yılmaz, Levent; Ozbelge, H. Onder (Informa UK Limited, 2009-01-01) 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 i...
Treatment by nanofiltration of the bleed stream of a continuous alcohol fermentor Aydogan, N; Gurkan, T; Yılmaz, Levent (Informa UK Limited, 2004-01-01) In continuous ethanol fermentation processes, which include product removal and recovery steps, to limit the concentration of secondary products, a bleed stream may be used. This stream contains several small molecular weight organic fermentation products and substrate sugars. To recover sugars and to minimize the amount of waste, the bleed stream is treated by nanofiltration. Three types of membranes were used in these experiments: 500 and 200 mwco (molecular weight cut off) polyamide and a thin-film compo...
