Кафедра "Бiотехнологiя, біофізика та аналiтична хiмiя" була створена у 1998 році на базі кафедри "Аналітична хімія", яка у 1940 році була виділена з кафедри хімії в самостійну кафедру. Ініціатива створення кафедри належить доктору технічних наук, професору Миколі Федосовичу Клещеву.

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут". Кафедра провадить освітню, методичну та наукову діяльність у галузі знань "Хімічна та біоінженерія". Крім теоретичних основ біотехнології, велику увагу було приділяється контролю якості і сертифікації біотехнологічної продукції.

У складі науково-педагогічного колективу кафедри працюють: 2 доктора наук: 1 – технічних, 1 – фармацевтичних; 8 кандидатів наук: 3 – біологічних, 5 – технічних; 2 співробітника мають звання професора, 6 – доцента.

Fatty acid monoglycerides are a valuable component of the products of various industries. The emulsifying ability of monoglycerides is used in cosmetic, pharmaceutical, and food production. The process of fatty acid monoglycerides obtaining by the reaction of vegetable hydrogenated fat (salomas) with glycerol (glycerolysis method) has been studied. Potassium glycerate is used as a catalyst, which is characterized by high efficiency and safety of production and use. A feature of the work is the study of the dependence of the yield and melting point of monoglycerides on the technological parameters of glycerolysis. As a raw material, hydrogenated refined fat according to DSTU 5040 (CAS Number 68334-28-1) was used: melting point – 48 °C, mass fraction of moisture and volatile substances – 0.08 %, acid value – 0.25 mg KOH/g, peroxide value – 2.8 ½ O mmol/kg. In all experiments, the glycerolysis temperature was 180 °C, the catalyst concentration – 0.5 % in terms of metal. Rational conditions for glycerolysis were determined: duration (90 min.) and glycerol concentration (50 %). Under these conditions, the monoglycerides yield was 32.9 %, melting point – 61.5 °C. The mass fraction of free glycerol in monoglycerides was 1.0 %, acid value – 2.2 mg KOH/g. The efficiency of monoglycerides obtaining using potassium hydroxide and glycerol mixture as a catalyst under certain rational conditions has been studied. The monoglycerides yield of 30.1 %, melting point of 59 °C were obtained. Therefore, the use of potassium glycerate catalyst is more efficient. The results of the study make it possible to improve the technology for the production of fatty acid monoglycerides using a new catalyst and use resources rationally.
Purification of Cr(VI)-containing wastewater by chemical precipitation: test results of an experimental-industrial installation
(Український державний хіміко-технологічний університет, 2021) Suvorin, A. V.; Shorokhov, M. N.; Ozheredova, M. A.; Bliznjuk, O. N.; Ryshchenko, I. M.; Masalitina, N. Yu.
We present the main results of experimental and industrial study of the developed process and pilot plant for purification of the Cr(VI)-containing rinse water by chemical precipitation. This technique implies full or partial return of treated water to rinse workpieces after chromium plating and prepare working solutions (precipitators). We characterize the manufacturing scheme of the pilot plant and the mode of its performance. Saturated aqueous solutions of Cа(OH)₂ and Bа(OH)₂ were used as precipitating reagents. The tests confirmed the possibility of automatic dosing the reagents with due regard for the pH value of a medium, which can be used in both continuous and periodic rinsing. The operating conditions of rinsing the workpieces after electrochemical chromium plating were justified. We derived the equation for the calculation of the total salt content in the rinse water after its purification. We determined the duration of the rinsing without the need to renew the bath volume. The performed calculations substantiated the possibility of reducing the consumption of fresh water supplied for rinsing by the recycling of wastewater without deteriorating the quality of the rinsed workpieces. The reduction of water consumption by 35% was observed as compared with that stated by the regulations.
