Use of supercritical
fluids in the inorganic analysis
Abstract
The opportunities, advantages, lacks and
prospects of use supercritical fluids for division and extraction of complexes
of metals with organic reagents are considered. The theoretical bases
supercritical fluid chromatography and factors influencing division of
complexes of metals (a nature of organic reagent, solubility of reagents and
complexes in supercritical fluid, type of a column, motionless phase, additive
of the modifier in a mobile phase, solvent of test) are discussed. The
processes occurring to complexes in time of chromatography are discussed. The
bases supercritical fluid extraction and factors influencing extraction of
metals (a nature and solubility in supercritical fluid of organic reagent and
complexes, concentration and ways of input reagent in system, additive of the
modifier, water, superficial - active substances, collector, matrix) are
considered. The opportunities of methods for definition of metals in various
objects are shown.
