Information for potential partners

The Department has considerable experimental material of studying patterns and features of the adsorption interaction of multiply charged metal ions, organic substances (organic dyes, surfactants, etc.) with surface of solid carrier of different nature. The experimental and theoretical results can be used in the development and improvement of express sensitive test methods for determination of inorganic and organic pollutants in natural and industrial waters. The other scientific interest of investigation is theoretical and experimental developments on main peculiarities at direct electrothermal atomic absorption determination of some heavy metals in solid, powdery and high-purity materials, as well as the use of matrix modifiers and other chemically active reagents in the analysis of environmental objects, products of non-ferrous metallurgy, biological and plant materials, food products. In recent years the department has been actively studying the possibility of using chromaticity functions for research and quantitative description of acid-base equilibrium in organic dyes solutions.

Historiography

The Department of Analytical Chemistry as an independent educational, methodical and scientific subdivision was found in 1933 in Odessa Novorossiyskiy University. The first Head of Chemical Faculty and at the same time Department of Analytical Chemistry was Prof. V.D. Bogatsky. Under his management the collective of researchers was actively engaged into studying of chemical analysis methods, especially organic analysis as well as application of organic reagents into inorganic analysis. Actually in the first years of faculty existence Prof. V.D. Bogatsky had been attempted to lay the foundation of traditional research activities “Organic reagents in analytical chemistry” which has been continued up today.

From 1941 to 1956 Ph.D. R.L. Dremluk was the Head of Department of Analytical Chemistry. At this time, scientific researches have been continuing the course of organic reagents studying at the analysis of anionic and cationic substances composition.

During the 1956-1968 under leadership of Prof. O.O. Morozov the new scientific direction was developed: “Chromatography studying of ion-exchange processes on liquid and solid ionites”.

From 1968 to 1971 (Head – Prof. A.M.Andrianov) the opportunity of organic reagents application for determination of rare elements was investigated.

In 1971-1984 Department of Analytical Chemistry was headed by doc. N.L. Olenovich, Ph.D. At this time the research activities was successfully continued on application of organic reagents at determination of elements III-V of groups of Periodic system, ion-exchange concentration and separations some of heavy metals from alkalis and acids solutions as well as organic solvents. Simultaneously atomic spectroscopy investigations on emission and atomic absorption analysis of high-purity materials, non-ferrous metals and alloys, refractory metal oxides and environmental have been started.

Since 1984 the Department of Analytical Chemistry was headed by doc. O.M. Chebotarev, Ph.D. The course of research studies from this time are devoted to efficient combination of concentration, separation and determination methods microquantities of components in various nature. The most important scientific achievements are related to the study of chemical-analytical and sorption properties of polyfunctional sorbents based on ion exchange resins and amorphous silicas with respect to multicharged metal ions. The developed sorption-spectroscopic methods for determination of heavy metals in natural waters, elements-analogues of subgroups of aluminum and titanium in industrial materials and natural objects deserve special attention. An important place in the scientific work of the department is occupied by research on the improvement and unification of methods of atomic absorption determination of heavy metals in food products, physiological fluids and substrates. Since 2006, the department has been intensively working on the theoretical substantiation and practical application of the method of chemical colorimetry in analytical chemistry using colorimetric functions to study the acid-base equilibria of organic dyes and complexation processes in solutions.

Since 2019, due to the reorganization of the Faculty of Chemistry and the opening of specialty 226 “Pharmacy. Industrial Pharmacy” Department was renamed to the Department of Analytical and Toxicological chemistry.

Since 2021, the Department of Analytical and Toxicological Chemistry has been headed by Assoc. T.M. Shcherbakova, Ph.D.
