Thallium-containing mineral systems. Part II: thallium and silver sulfosalts with applications to polymetallic ores
(Chemie der Erde-geochemistry, 1993)
An experimental program was initiated to study the formation of Tl-sulfosalts in comparison with silver. This process is controlled by the activity of arsenic and/or antimony and/or bismuth contents. Generally thallium ...
The photoelectron spectra of some Tl-Sb sulphosalts
(Physics and Chemistry of Minerals, 1993)
The results of X-ray induced photoelectron spectroscopy (XPS) experiments on several phases of the ternary system Tl-Sb-S are reported. The binding energies of the inner S, Sb and Tl electrons increase with increasing ...
Effect of electronegativity of donor atoms on RF values of tris(β-diketonato) complexes of cobalt(III), chromium(III) and ruthenium(III) by thin-layer chromatography on silica gel
(Chromatographia, 1993)
The effect of the electronegativity of donor atoms on RF values obtained by TLC on silica gel was investigated with two series of complexes of the type [M(acac)3-n(phacphac)n] and [M(acac)3-n(phacphSac)n], where M is ...
A kinetic investigation of the tris(4-morpholinecarbodithionato-S,S') cobalt(III) complex formation by the intralattice and interlattice reactions
(Thermochimica Acta, 1993)
The kinetics of tris-(4-morpholinecarbodithionato-S,S) cobalt(III) formation by the intralattice and interlattice reactions of hexaaminecobalt(III) cation with dithiocarbamato anion was investigated under isothermal ...
Sesquiterpene lactone from Achillea crithmifolia
(Planta Medica, 1993)
Investigation of the catalytic effects of indigenous minerals in the pyrolysis of Aleksinac oil shale substrates: Steranes, triterpanes and triaromatic steroids in the pyrolysates
(Organic Geochemistry, 1993)
Evidence for catalytic effects of indigenous minerals in the pyrolysis of Aleksinac oil shale kerogen was found by investigating the liquid products obtained in the Micro Activity Test (MAT) pyrolysis of raw shale and its ...
Structural analysis of the secondary school chemistry textbook / Stručna analiza srednjoškolskog udžbenika hemije
(Nastava i vaspitanje, 1993)
The object of analysis was M. Rakočević and R. Horvat's General Chemistry for the First Grade of Secondary School, Zavod za izdavanje udžbenika Novi Sad, Stručna Knjiga Beograd, 1992 Fifth edition). The analysis was carried ...
