ELECTROCHEMICAL OXIDATION OF NITROGEN (II) OXIDE IN THE NEUTRAL MEDIUM
(Natl Acad Sci Republic Kazakhstan, 2019)
Electrochemical oxidation of nitrogen oxide was considered in the work. The study was carried out in the sodium sulphate solution. The effects of current density in the anode, electrolyte concentration, granular electrode ...
DISSOLUTION OF STAINLESS STEEL UNDER ALTERNATING CURRENT POLARIZATION
(Natl Acad Sci Republic Kazakhstan, 2018)
The present work studies the dissolution of stainless steel electrode (12X18H10T) under alternating current polarization with frequency of 50 Hz in sulfuric acid solution. The impact of the current density (200-1200 A/m(2)) ...
The identification and quantitative analysis of the very toxic 2,3,7,8-tetrachlordibenzo-P-dioxin in the presence of polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) contaminated soil samples
(Marcel Dekker Inc, 1999)
This research decribes the nature and extent of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) contamination in the soil samples from a waste cable incineration plant. The samples are collected at different places in ...
Solvent extraction of Fe3+ cation by 25,26,27,28-tetraisonitrosoaceto calix[4]arene and based ligands
(Marcel Dekker Inc, 1999)
25,26,27,28-Tetraisonitrosoaceto calix[4]arene [L-8] was synthesized by reacting 25,26,27,28-tetraacetyl calix[4]arene [L-7] with n-butyl nitrite. The synthesized compounds [L-7, L-8] and based ligands (p-tert-butyl phenol ...
Antimicrobial effects of bis(Delta(2)-2-imidazolinyl)-5,5 '-dioxime and its mono- and tri-nuclear complexes
(Kluwer Academic Publ, 2000)
Bis(Delta(2)-2-imidazolinyl)-5,5'-dioxime (H2L) and its nickel, cobalt, zinc, cadmium and mercury complexes have been prepared and tested in vitro against different microorganisms in order to assess their antimicrobial ...
Synthesis of a novel heterocyclic dioxime and its mononuclear complexes with Ni(II), Co(II), Cu(II), Zn(II), Cd(II) and Hg(II)
(Marcel Dekker Inc, 1999)
In this work, a novel heterocyclic dioxime (2,3-hydroximino-4-phenyl-6-phenlyazo-1-thia-4,5-diazacyclohexa-5-diene, H2L) was synthesized by reacting dithizone with cyanogen di-N-oxide. H2L forms mononuclear complexes ...
ELECTROCHEMICAL BEHAVIOR OF SILVER IN A POTASSIUM FERROCYANIDE SOLUTION
(Natl Acad Sci Republic Kazakhstan, 2020)
One of the main priorities of the innovative industrialization of the country is the development of metallurgy and the production of finished products. In this regard, the application of new methods for producing metals ...
