The theory and ways of applying a new electroanalytical detectior
method were developed. The method, called galvanovoltammetry,
consists of the measurement of current from the bipolar electrode of
a three electrode cell which consists of a working electrode and a
counter electrode, between which a constant current is applied, and...
The extraction of tantalum fluoride complexes by large cationic
extractants (tetraphenylarsonium ion, TPA, and crystal violet) and
by methyl isobutyl ketone (MIBK) has been investigated as a function
of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the
cationic extractants into chloroform were carried out in the absence
of...
A procedure is described for the optimization of a previously
described continuous analysis adaptation of the Pearl-Benson or
nitroso method for estimation of spent sulfite liquor (SSL) or ligno-sulfonates.
The optimized procedure has a response time of 6.5 minutes. In order to monitor samples whose SSL concentration is
between 0...
An instrument was developed which performs analysis of the
oxygen content of air by means of a commercial polarographic oxygen
electrode. The oxygen analyzer is part of a portable instrument
which converts the current from the oxygen electrode into a pulse
whose width is proportional to the oxygen concentration. This...
