The dissolution of iron under cathodic polarization
(Pergamon Press, 1979)
It has been shown that the dissolution rate for iron at cathodic potential is higher than expected on the grounds of the Wagner-Traud mixed potential theory. This observation cannot be explained by a parallel chemical ...
Powdered sample analysis in a double plasma arc source in a graphite tube
(Elsevier, 1977)
A double plasma d.c. arc burning in a horizontal graphite tube in a magnetic field was developed as a light source for spectrochemical purposes. It was demonstrated experimentally that a prolongation of the residence time ...
The effect of the plasma composition on characteristics of the d.c. arc-II. Arc in argon and arc in nitrogen with water vapour
(Elsevier, 1971)
The experimental and theoretical curves of the radial temperature distribution of the arc burning in argon, are compared with the corresponding curves in nitrogen. The theoretical curves are obtained by solving the ...
The effect of the plasma composition on characteristics of the d.c. arc-III. Arc in carbon dioxide
(Elsevier, 1971)
The experimental and theoretical curves of radial temperature distribution of the arc burning in carbon dioxide, compared with corresponding curves in nitrogen, are considered. The theoretical curves are obtained by solving ...
Extractives of Artemisia scoparia
(Elsevier, 1973)
Artemisia scoparia collected south of Belgrade was used. Capillin, 1-phenyl-2,4-hexa-diyne-1-ol, vanillin, and scoparone were isolated. All compounds were identified by direct comparison with authentic materials, by m.m.p., ...
Rotating two-ring electrodes as a tool for electrochemical investigations of gas-evolving reactions
(Elsevier, 1972)
It is shown that two concentric ring electrodes located on a rotating disc surface can be used as an instrument for chemical and electrochemical analysis of gas-evolving reactions up to rates of gas evolution from the inner ...
The polarographic behavior of metal ions in molten LiNO3-KNO3 eutectic in presence of complexon III
(Elsevier, 1973)
The possibility of using complexon III as a complexing substance in the polarography of salt metls (LiNO3-KNO3 eutectic) has been investigated. Complexon III was found to form complexes with Cd, Pb, Ni and Zn ions in the ...
Synthesis and solution properties of poly(diphenyl itaconate)
(Elsevier, 1976)
Solid diphenyl itaconate monomer was obtained by esterification in the presence of diphosphorus pentoxide and polymerized in bulk with AIBN as initiator. The non-film forming polymer powder was characterized by fractionation, ...
Direct solution analysis using an arc source incorporating two plasmas rotating in a graphite tube
(Elsevier, 1977)
As a continuation of earlier work on arc sources for the spectrochemical analysis of powdered samples, a source appropriate for multi-element analysis of trace elements in solution has been developed. The nebulized solution ...
Acetoxylation of steroidal lactones by means of lead tetraacetate
(Elsevier, 1970)
One of the structural features of many bitter principles ls the presence of a &-lactone ring. Some of these compounds differ from one another by the state of oxidation of the molecule as a whole and also by the state of ...
