Reagents obtained by our methods are of great benefit to the economy
– Before talking about a scientific topic, it seems to me that I need to tell you how I got on the path of science. From my age, I was passionate about books, I was eager for knowledge. It was then that I had a big dream. As if I understood from childhood that education leads to a bright future. Although I still did not freely understand who I would become, what profession I would become, thoughts often came to me: "I will become a big person, a well-known, popular person". I also remember that when I was little, I read about the Kazakh State University named after S. M. Kirov in the newspaper "Kazakhstan pioneer" and said to my mother: "Mom, when I grow up, I will enter KazGU". I graduated from a Russian school in North Kazakhstan region with a gold medal and went to Almaty. I was admitted to the Faculty of Chemistry of Al-Farabi Kazakh National University, this great educational institution. At this faculty, we studied under legendary teachers — B. Birimzhanov, A. Sharifkanov, M. Kozlovsky, M. Usanovich, O. Songina — and their students N. Nurakhmetov, A. Zebreva, E. Ablanova, Kh. Ospanov, and other well-known scientists”,- says Azhar Kospankyzy.
After graduation, she went to Karaganda State University, where entered the future as the second university in the Republic at that time. She graduated from graduate school under the guidance of a great teacher, a well-known scientist in the field of chemistry and Metallurgy Evney Buketov.
- I completed a scientific internship at the same chemical and Metallurgical Institute in Karaganda. At this institute, I received training from scientists who deal with various difficult problems in the production facilities of Kazakhstan. Walking here, I met my life partner. She is a doctor of chemical sciences, professor, academician of the National Academy of Sciences of the Republic of Kazakhstan Abduali Baeshov. To this day, we work together on the path of science. In this scientific center, we took the initiative of our future scientific work, and since then we continue to engage in research. In the widely developed copper production in Kazakhstan, many by-products are formed in the process of processing ore and obtaining pure copper. Among them, precious metals – gold, silver, as well as selenium and tellurium, which are rare elements, accumulate in the form of sludge. Copper powder is also formed in the slime. The problem of extracting these precious chemical elements was considered very difficult. The topic of my Ph. D. thesis was devoted to the study of the electrochemical properties of copper and selenium contained in these sludge. During the experiments, we developed a method for reducing hexavalent selenium, separating it in the state of a pure element, and protected it with the copyright certificates of the USSR", – says Azhar auntie.
The topic of the scientist's doctoral dissertation is devoted to the development of methods for obtaining their valuable compounds from the remains of a number of metals, including hard-melting titanium. She received a number of patents in this direction. Among them, one can single out the patent of the Eurasian patent Bureau. Compounds of titanium, lead, copper, iron and other metals, namely oxides, hydroxides, salts, are used in various fields. And obtaining them by certain methods is carried out with various difficulties. Requires driving at high temperatures. They are multi-stage and are implemented with the use of a number of harmful compounds.
- According to the methods developed by us, these chemical compounds are made at room temperature without the use of any additional reagents. These methods are environmentally and economically effective. In addition, in the course of studying the electrochemical properties of these metals, we also developed methods for extracting elements such as gold, silver, copper, selenium, tellurium in pure form from wastewater and used solutions at production sites. The development of these methods is carried out with grant funding from the Ministry of Science and higher education of the Republic of Kazakhstan. The allocated funds provided the laboratory with equipment, reagents and research. These studies are not a day or two of work. It takes months, years to get real results from them. Today, the results of research are protected by patents and published in such works as articles in domestic and foreign journals, monographs. At the same time, graduation works of students, master's and PhD dissertations are being defended. Right now, it is difficult to assess the benefits for the country, for our development, for the economy. However, if we focus on the areas of application of many metal compounds, the reagents obtained by the methods we have developed will certainly benefit the economy, – says the scientist. – On the one hand, these compounds are not profitable to this day, they provide for the processing of accumulated scrap metal, chips, and therefore environmental purification, on the other-the synthesis of the most necessary chemical compounds in cheap, effective ways. Now the direction of synthesis of inorganic compounds by electrochemical methods is of interest to a number of production facilities. At the same time, in the course of studying the electrochemical properties of copper, we developed methods for obtaining ultrafine, ultrafine powders of this metal, which are widely used in various industries, and received several patents. These powders were produced and put up for sale by the institution "Grand Metal Corporation" LLP.
The second aspect of a scientist is the teaching path. It is important to teach others what you know, to educate young people. Under the scientific supervision of Azhar Khostanovna, 4 candidate dissertations, more than 70 master's theses and 100 theses were defended. She repeatedly analyzed candidate and doctoral dissertations as an official opponent, prepared reviews, and was also a member of dissertation councils. The professor has more than 700 scientific, educational and methodological works, author's certificates and patents. Teaching aids in chemistry and ecology in the Kazakh language are now useful for students.
Many years of scientific research have paid off over time. The scientific community appreciated her work. In 2003, she became a laureate of the state prize of the Republic of Kazakhstan in the field of Education, Science and technology and was awarded the academician E. A. Buketov prize. In addition, she became the winner of the competition "K.A. Yasawi University", "the best teacher of the University", "honorary worker of Education of the Republic of Kazakhstan", and was awarded the title of “Best Inventor and Rationalizer” by the All-Union Society of Inventors. She is also an academician of the International Academy of Informatization.
