The purpose of this work is to develop a methodology for analysis and control of microcomponents in order to achieve high selectivity and correctness of their determination. Research methods - atomic absorption with flame and electrothermal excitation, mass spectrometry with inductively coupled plasma, etc. The main results: calcined layered double hydroxides Mg and Fe(III) for sorption preconcentration of phosphate ions and their photometric determination in natural waters, conditions and mechanisms for extracting and eluting phosphate ions have been studied. The results of the search for selective and express methods for the determination of bromide ions suitable for monitoring sources of drinking water supply are presented. The method for the determination of active radical forms of oxygen in bicarbonate aqueous solutions activated by vacuum ultraviolet radiation has been developed. A method for determining the critical concentrations of humic acids in aqueous solutions, which cause their structural transformations, is developed. The disperse-phase state of polycyclic aromatic hydrocarbons in the water of rivers of Ukraine is established. Field of application - environmental protection.
