Chelate extraction of transition metal ions by ethylene diamine diacetic acid with n-substituted octadecyl groups
Bıçak, Niyazi; Şungur, Şana Kutun; Tan, Nükhet; Gazi, Mustafa (Taylor & Francis Inc, 2002)An organic-soluble chelating agent NN'-di-n-octadecyl ethylenediamine-NN'-diacetic acid (DOED) has been synthesized in two steps by (i) condensation of dibromoethane with 1-amino octadecane (octadecylamine) and (ii) ... -
A glycidyl methacrylate-based resin with pendant urea groups as a high capacity mercury specific sorbent
Bıçak, Niyazi; Sherrington, David C.; Şungur, Şana Kutun; Tan, Nükhet (Elsevier Science Bv, 2003)Polymer-supported pendant urea groups have been demonstrated to be very efficient in selective removal of mercuric ions from aqueous solutions. Methyl methacrylate (0.5 mol)-glycidyl methacrylate (0.4 mol)-divinylbenzene ... -
Metalization of polymer beads via polymer-supported hydrazines as reducing agents
Bıçak, Niyazi; Şungur, Şana Kutun; Tan, Nükhet; Bensebaa, Farid; Deslandes, Yves (John Wiley & Sons Inc, 2002)A new method for depositing metal onto a polymer surface has been developed in which the metal coating of polymer beads is performed with hydrazine functions as reducing agents on the surface of the polymer itself. In this ... -
The stability constants of the rare earth complexes with trimetaphosphoric acid
Şungur, Şana Kutun (Soc Chimica Italiana, 2001)The stability constants of the complexes formed between the rare earth metal ions and the anion of trimetaphosphoric acid have been determined at a temperature of 20 degreesC and an ionic strength of mu =0.1 by the ...
