Thin-layer chromatography of mixed tris-beta-diketonato metal complexes on polyacrylonitrile sorbent
(Elsevier Science Bv, Amsterdam, 1999)
The effect of the composition of mixed tris-beta-diketonato metal complexes on their hR(F) Values obtained by a thin layer of polyacrylonitrile sorbent was examined with two series of complexes of the type [M(acac)(3-n)( ...
Thin-layer chromatography on polyacrylonitrile. V. Consideration of separation mechanisms of some aliphatic and aromatic amines
(Journal of Chromatography A, 1992)
The chromatographic behaviour of ten aliphatic and aromatic amines on thin layers of polyacrylonitrile sorbent was investigated using seven aqueous solvent systems. It was established that an increase in the hydrophobic ...
Planar chromatography of facial and meridional isomers of some aminocarboxylato cobalt(III) complexes
(Springer Hungarica Kiado Kft, Budapest, 1997)
Effect of the chelate ring size of diamine-Co(III) complexes on their hR(F) values obtained under salting-out thin-layer chromatography conditions
(Elsevier Science Bv, Amsterdam, 1999)
The effect of the chelate ring size of diamine Co(III) complexes under salting-out thin-layer chromatography (TLC) conditions was investigated. For that purpose, 16 neutral and cationic complexes containing from five- to ...
Thin-layer chromatography of facial and meridional isomers of Co(III) and Cr(III) complexes on polyacrylonitrile sorbent
(Elsevier Science Bv, Amsterdam, 1999)
The effect of facial-meridional geometrical isomerism of metal complexes on their chromatographic behaviour on a thin layer of polyacrylonitrile sorbent was examined. To that purpose the three following series of complexes ...
Thin-layer chromatography on polyacrylonitrile. IV. Investigation of the separation mechanisms for tris-(alkylxanthato)cobalt(III) complexes
(Journal of Chromatography A, 1992)
The chromatographic behaviour of six tris(alkylxanthato)cobalt(III) complexes on polyacrylonitrile sorbent thin layers was investigated using four non-aqueous and two aqueous solvent systems. It was assumed that their ...
Effect of increasing the bidentate chelate ring size in Co(III) complexes on their behavior in salting-out TLC on different adsorbents
(Springer Hungarica Kiado Kft, Budapest, 1999)
The effect of enlargement of the chelate ring size in Co(III) complexes containing bidentate aminocarboxylato and/or diamine ligands on their R-F values in salting-out chromatography has been investigated on thin layers ...
Physicochemical and immunologic characterization of low molecular-weight allergoids of Dactylis glomerata pollen proteins
(Munksgaard Int Publ Ltd, Copenhagen, 1999)
Background: Orchard grass (Dactylis glomerata) pollen proteins were chemically modified by means of acid anhydrides (maleic and succinic anhydride) to obtain low-molecular-weight allergoids. Chemical modification in both ...
Different serum insulin-like growth factor-1 (IGF-1) binding characteristics accompany reduced growth associated with low thyroid hormone and/or low total IGF-1 status in young pigs
(Veterinary Faculty, Belgrade, 1998)
Serum IGF-I binding patterns were determined for 3-month-old pigs exhibiting a wide range of total IGF-I and thyroid hormone (TH) concentrations. Both variables positively correlated with their growth No differences in ...
Проверавање знања и вештина кроз експерименталне задатке / The evalutation of knowledge and skills through experimental problems
(Српско хемијско друштво, 1999)
The practical examination involves wide range of pupils¢ activities and provides the evaluation of their theoretical knowledge and achieved level of the laboratory skills.
However, it should prove to be one of the most ...
