Alemasova A. The high temperature processes of complexing reagents and complexes' transformation during atomic absorption analysis.

The metrological characteristics of metals microquantities atomic absorption determination in environmental and industrial objects. To investigate methods of detection limit decreasing and precision increasing of metals atomic absorption determination by means of chemical modification of high temperature processes of free atoms formation. The methods of investigation - thermogravimetry, spectrophotometry, X-ray difraction, IR-spectroscopy, flame and electrothermal atomic absorption, ESR-spectroscopy. The new concept of modification of atomization processes was developed. Principally new complexing and metal complex modifiers, the mechanism of thermal stabilization and the ways of metal compounds atomization in the presence of modifiers were proposed. The sensitive high accurate and express electrothermal and flame methods of metals determination were worked out and put into practice on USRI of salt industry, Donetsk and Makeevka metallurgical plants and so on. Application spheres: black and colour meta llurgy, ecological monitoring, food industry.
