Abstract

The article is dedicated to the 70-years-old jubilee of a well-known electrochemistry scientist, Doctor of Chemical Sciences, professor V. F. Vargalyuk. The article reflects the main milestones of his life and career. More than 50 years of Viktor Fedorovich's life are connected with the chemistry department of the Oles Honchar Dnipro National University, where he came as a student. He started his scientific activity as a student at the Department of Physical Chemistry under the guidance of a famous specialist in the field of electrochemistry prof. Yu. M. Loshkarev. Studying the interactions of surface-active complexing agents in practically important processes, V. F. Vargalyuk made a significant contribution to the development of the theory of the influence of these substances on the kinetics and mechanism of electrochemical reactions. For a long time he was in charge of the research laboratory of electrodeposition of metals, which is certified by the International Corrosion Council among the world's leading anti-corrosion research laboratories. V. F. Vargalyuk's organizational activity as the dean of the chemical faculty of Oles Honchar Dnipro National University, who he has been for almost a quarter of a century, is revealed. Victor Fedorovich is able to respond to the challenges of time quickly and adequately and find the most optimal ways to develop the faculty. The article also mentions the pedagogical achievements of V. F. Vargalyuk. He has developed and implemented in the educational process more than 20 various general and special courses in almost all sections of chemistry-inorganic, physical, colloidal, food, computer, and crystal chemistry.

“…Титан (IV) оксид є одним із найрозповсюджених білих пігментів, що має широке застосування у виробництві товарів різного призначення, зокрема титанових білил, пластичних мас та матеріалів на їх основі, каучуку, гуми, лінолеуму, паперу, картону, шпалер, синтетичних волокон тощо [1]. Сульфатний метод виробництва титан (IV) оксиду, що базується на розкладанні титановмісної руди сульфатною кислотою, з утворенням розчинів сульфатів титану, заліза та інших металів, із подальшим їх гідролізним очищенням від домішок, є основним методом отримання ТіО 2 у більшості європейських країн [2].…”
