SELECTIVE EXTRACTION OF IRON CHLORIDE COMPLEX (III) AND ITS COMPLEXIZATION FROM 5-( PYRIDILAZO)-2-(MONOETHYLAMINE-PARACRESOL) (PAAC) DIRECTLY IN THE ORGANIC PHASE

The developed method of extraction-photometric determination of iron with PAAC differs from the existing selectivity, sensitivity, simplicity and rapidity and is recommended for the analysis of production solutions, waste water, ores, concentrates and other chemically complex materials without separation of accompanying elements directly in the organic phase.
