The Department of Analytical Chemistry of Lviv University is classic department of analytical chemistry with long-term traditions combined with modern approaches and innovative trends. The department provides the teaching of theory and the development of practical skills from chemical, physico-chemical and some physical methods of analysis necessary to become highly professional experts in analytical chemistry.
History of Department
A Brief History of the Department of Analytical Chemistry
The Department of Analytical Chemistry was created in 1944-45. F. Pless, Y. Grabovsky, Y. Schramm, B. Liakhovich, S. Tolochko and S. Weisberg were the first professors at the Lviv University who taught analytical chemistry in German at the Faculty of Philosophy (since 1851) and later at the Faculty of Medicine (since 1895).
Shevchenko Scientific Society and especially its Section of Mathematical, Natural and Medical Sciences played an important role inspreading knowledge in analytical chemistry and other sciences. The Section of Mathematical, Natural and Medical Sciences organized the lectures on various issues of natural science, and since 1897 began to publish scientific journal “Collection of Section of Mathematical, Natural and Medical Sciences ofShevchenko Scientific Society”. The 32 volumes were published.
Prof. Tzhebyatovsky V. and Kemul V. taught analytical chemistry at the beginning of the twentieth century. Since 1931 Kemul V. introduced polarography to determine small quantities of substances and began to investigate the effect of surface-active substances on electrode processes as well.
The first head of the Department of Analytical Chemistry was Assoc. Prof. Krugovy N.S. (1945–1946). Afterwards, the department was headed by Assoc. Prof. Zolotukhin V.K. (1946-1962), Assoc. Prof. Golovaty R.M. (1962-1970), Assoc. Prof. Zinchuk V.K. (1970-1972), Prof. Kuzma Yu.B. (1972-2003), Assoc. Prof. Chikhrii S.I. (2003-2005), Prof. Kalichak Y.M. (2005-2014). Assoc. Prof. Dubenska L.O. heads the department since 2015.

The research work of the Analytical Chemistry Department was carried out in the following areas: sorption of rare earths on zeolites and the development of new methods for the determination of rare earths in natural objects; complexation of metals with organic reagents (azodyes, derivatives of azolidones, oximes, etc.) and their application in voltammetry; development of methods for quantitative determination of pharmaceutically active substances (anesthetics, antibiotics, etc.) using spectrophotometry and voltammetry; physical and chemical analysis of the systems of rare-earth – transition metal – p-element of III or V group: synthesis, structure and properties of compounds (construction of isothermal sections of the state diagrams, synthesis of new compounds, investigation of the crystal structure and physical properties of selected compounds).
Development of voltammetric methods for determination and detection of medicines in real objects: pharmaceutical preparations, biological fluids etc. Investigation of derivatization reactions to obtain new analytical forms available for voltammetric determination and detection of medicines. Study of electrochemical characteristics of medicines’ analytical forms on the different nature electrodes (DME, some stationary electrodes).
Research topic ХА-87 Ф “Multifunctional materials clinoptilolite – transition metals in chemical analysis and biology”.
Scientific head – Prof. Kalychak Ya.M.
The sorption behavior of Pr(III), Gd(III), Lu(III) from aqueous solutions using natural and H-forms of Transcarpathian clinoptilolite have been studied. The methods of Pr(III), Gd(III) and Lu(III) concentration using solid phase extraction are proposed. The conditions for the separation of Gd(III) and Tb(III), which belong to the yttrium group were found using H-clinoptilolite. The optimal conditions for the process of platyphilin oxidation by 2KHSO5∙KHSO4∙K2SO4 have been determined. A voltammetric method of the alkaloid platyphylline determination is developed. The oxidation product is most probably the platyphylline N-oxide, which is capable to reduction on the mercury dropping electrode. The amoxicillin interaction with the sulphanilic acid, sulphanilamide, sulphathiazole and benzidine has been studied. On the basis of the established optimal reaction conditions new methods of amoxicillin spectrophotometric determination were developed. The selectivity of amoxicillin spectrophotometric determination in the presence of auxiliary substances (excipients and preservatives) and bioactive substances has been investigated. The elaborated methods have been approved during the analyses of model solutions and the single- and multicomponent medicinal formulation. The antimicrobial properties of clinoptilolite in compositions with Ag+ and Mn2+ toward typical strains of the pathogenic gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa were investigated. Screening for survival of epitheloid cell lines (carcinoma), mesenchymal cell lines (glioma), pseudonormal mouse fibroblasts cell line NIH 373 and human embryonic kidney cell line HEK 293 in the presence of zeolites spiked with mono-(Ag+), di-(Cu2+, Zn2+), tri-(rare earths: Gd3+, Ga3+, Lu3+, Tb3+, Yb3+, Ce3+, Nd3+)valent cations using MTT assay has been carried out. It is established that the most signified toxic effects have samples with silver. The effect of inhibition of biomass growth has a weak dose-dependent effect, which suggests that the cytostatic process predominates over its own toxicity.
