Bazı metal katyonlarının katı-sıvı ekstraksiyonu
Güngör, Ayla (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2000)Geçiş metallerinden Cd(II), Co(II), Ni(II) ve Pb(II) nin parafın (e.n.58- 60°C) ortamında N,N-dibutil-N'-benzoiltiyoüre (DBBT) ligandı kullanılarak ekstraksiyon davranışları 65,0 ± 0,5 °C de incelendi. Her metalin ekstraksiyon ... -
Extraction of some transition metals with N,N-dibutyl-N '-benzoylthiourea into molten paraffin at 65 degrees C
Merdivan, Melek; Güngör, Ayla; Savaşcı, Şahin; Aygün, Rüveyde Sezer (Elsevier Science Bv, 2000)The solid-liquid extraction behaviour of some transition metals (Cu(II), Co(II), Ni(II), Cd(II) and Pb(II)) by the use of N,N-dibutyl-N'-benzoylthiourea as an extractant in paraffin (58-60 degrees C) has been investigated ... -
Flame AAS determination of platinum, palladium, and rhodium in catalysts
Merdivan, Melek; Aygün, Ruveyde Sezer; Külcü, Nevzat (Perkin-Elmer Corp, 1997)A flame atomic absorption spectrometric method is described for the determination of platinum, palladium, and rhodium in used and fresh alumina-supported and sieve catalysts. A lanthanum solution was used to eliminate ... -
Phosphonate-based resins for the selective enrichment of uranium(VI)
Merdivan, Melek; Buchmeiser, Michael R.; Bonn, Guenther Karl (Elsevier Science Bv, 1999)Phosphonate-derivatized polystyrene-divinylbenzene-based (PS-DVB) resins have been prepared from chloromethylpolystyrene-divinylbenzene (Cl-CH(2)-PS-DVB) by the Arbuzov-reaction using lithium or sodium alkyl chlorophosphites. ... -
Study of the thermal decompositions on N,N-dialkyl-N '-benzoylthiourea complexes of Cu(II), Ni(II), Pd(II), Pt(II), Cd(II), Ru(III) and Fe(III)
Merdivan, Melek; Karipcin, Fatma; Külcü, Nevzat; Aygun, Ruveyde Sezer (Kluwer Academic Publ, 1999)The thermal decompositions of the complexes of N,N-dialkyl-N'-benzoylthioureas with Cu(II), Ni(II), Pd(II), Pt(II), Cd(II), Ru(III) and Fe(III) were studied by TG and DTA techniques. These metal complexes decompose in two ... -
Thermal behaviour of some metal complexes of N,N-diethyl-N'-benzoyl thiourea
Merdivan, Melek; Aygun, Ramazan S.; Külcü, Nevzat (John Wiley & Sons Ltd, 1997)The thermal behaviour of the complexes of N,N-diethyl-N'-benzoylthiourea (DEBT) with NI(II), Cu(II), Pt(II), Pd(II) and Ru(III) was studied using differential thermal analysis (DTA) and thermogravimetry (TG). These complexes ... -
Thermal decomposition kinetics of some metal complexes of N,N-diethyl-n '-benzoylthiourea
Özpozan, Nilgün Kalaycıoğlu; Arslan, Hakan; Özpozan, Talat; Merdivan, Melek; Kulcu, Nevzat (Kluwer Academic Publ, 2000)Thermogravimetry (TG) and differential thermal analysis (DTA) were performed on the complexes with general formula (M(DEBT)(n) (where M=Fe, Co, Ni, Cu or Ru; n=2, or 3 and DEBT=N,N-diethyl-N'-benzoylthiourea). Derivative ...
