Description

Object of study - drinking, natural water, biota and particulated substances in river water. The purpose of research - development of selective and rapid methods for determination of toxic compounds in water systems including sediments and biota. Research methods - mass spectrometry with inductively coupled plasma (ICP-MS), high performance liquid chromatography with fluorescence detection (HPLC-FL), diffused reflection spectrometry (DRS), solid phase extraction, sorption on solid sorbents. Main results - new Zn/Al hydrotalkitic sorbent in Ca-form were synthesized and its properties for traces of Cr(VI) extraction from surface and underground water were investigated. The method for Cu, Zn, Pb, Ni, Cd, Cr, Mn determination in fish tissue were developed using microwave- assisted digestion and ICP-MS; the procedure were used for analysis of fish tissues from various Ukranian rivers and calculation the bioaccumulation factors for heavy metals from field study. Highly sensitive method for 16 priority polyaromatic hydrocarbons (PAH) determination by HPLC-FL was optimazed. Solid-phase extraction on porous polymeric sorbents achives concentration factor (1,4-2,8)·103 and detection limit - (0,1-1,0) ng/dm3. Procedure were used for determination of heavy PAH in Ukrainian rivers - Desna, Dnipro, Western and Southern Bug , and their distribution in river water between dissolved and particulated phases were investigated. New DRS method for the determining of bromates in drinking water have been developed; procedure includes sorption of colored ion associates of magenta and anionic surfactants on membrane filters and measurement of bromate by DRS. The optimal conditions were investigate for sorption of phenol in the polyurethane foam as colored compound with 4-aminoantipyrene and subsequent determination in sorbent phase with DRS. New method is proposed for photometric determination of anionic surfactant based on usage of methylene blue, polyurethane foam and RDS method for detection. Method adopted for the analysis of river water rich in humic substances, detection limit for sodium dodecylsulfate is equal to 0,007 мкМ, the range of linearity of calibration curve is (0,007 - 1,11) мкМ. Field of application - protection of public health, protection of environment.
