Investigation of the anodic processes on platinum in perchlorate and chlorate solutions by linear sweep voltammetry using the rotating double-ring electrodes
(Elsevier, 1976)
There have been several attempts to elucidate events occurring on platinum immersed into pure perchloric acid solutions, when submitted to high anodic polarisation. The polarisation curve was shown to exhibit two levels, ...
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 ...
Structural change in the zeolite inclusion complex through high temperature treatment. Denitrated zeolite
(Elsevier, 1976)
In the sodium nitrate melt, sodium zeolite, NaA, forms the
inclusion complex NaA.NaNO3[1,2] which contains sodium
nitrate molecules in the central a cage. Our earlier
investigations [3] of inclusion complexes have shown ...
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 ...
Mass spectrometric analysis of plasma composition of a D. C. arc burning in an air atmosphere / Massenspektrometrische Analyse der Plasmazusammensetzung eines Gleichstrombogens in Luft
(Springer-Verlag, 1979)
The plasma composition of a d. c. arc burning in air was investigated by mass spectrometry. It has been found that the CO and CO2 contents result from homogenous chemical reactions and that the content of carbon is about ...
New approach to the aromatization of ring B in 19-norsteroids and to the synthesis of equilenin-type compounds
(Royal Society of Chemistry, 1978)
When 7α-acetoxy-3,3 : 17,17-bis(ethylenedioxy)-5,10-epoxy-5β, 10β-oestran-6-one (2), formed by lead tetra-acetate acetoxylation of the parent compound (1), is heated with alkali, it undergoes ring B aromatization to give ...
Analysis of the organic matter of oil shales by nuclear magnetic resonance
(Pergamon Press, 1978)
13C NMR spectroscopy was applied in the investigation of the structure of the organic matter in oil shales. By using Proton Enhanced Nuclear Induction Spectroscopy, a fair resolution of aliphatic and aromatic carbon signals ...
A new type of d.c. arc as spectrochemical light source
(Elsevier, 1974)
A new type of d.c. arc light source for spectrochemical purposes has been developed. The horizontal arc burning in a graphite tube is placed in an inhomogeneous magnetic field. The limits of detection of In and Pb have ...
Einfluß der Anionen bei spektrochemischer: Spurenanalyse im lichtbogen
(Elsevier, 1971)
The influence of the addition of ammonia into the arc plasma on the spectral line intensities (with background correction) of trace elements was studied. The intensity changes caused by addition of ammonium sulphate and ...
Platinum-iridium catalyzed titanium anode. I. Properties and use in chlorate electrolysis
(Springer Science and Business Media LLC, 1975)
The use of dimensionally stable titanium anodes activated with Pt, Ir or ruthenium oxide for electrolytic chlorate production has been investigated. Simultaneous measurements were made of the amount of noble metal at the ...
