Purpose of the development: This invention relates to analytical chemistry, in particular to devices potentiometric determination tetra fluoroborates in solution.

Recommended application field: Chemical sensor can be used in the factory, research, chemical analytical laboratories that specialize in environmental protection, food industry, technology and medicine.

Advantages over analogues: Developed chemical sensor has better performance in comparison with analogues, which include the ability to use it to determine the activity of the ions tetrafluoroborates in strongly acidic solutions (up to 6 M H2SO4) and in the presence of many foreign substances, as well as a longer service life and less time response.

The development stage readiness: Pre-production model is made

Technical and economic effect: The starting materials for the synthesis elektrodoaktivnogo agents are commercially available, which considerably reduces the cost of the developed sensor in comparison with the conventional counterpart. Simplified procedure for obtaining the ion associate leads to a reduction of labor costs and, as a consequence, the competitive ability of the sensor.

Description of the development:
()
One of the most important analytical forms of boron tetrafluoroborate ion, which is formed from boron-containing materials when exposed to acidic fluoride solutions. Tetrafluoroborate anion is widespread in the technology in electroplating, synthetic organic and inorganic products. Nature elektrodoaktivnyh substances is an important factor that determines the basic metrological characteristics of the sensor. The object of the invention was to develop a tetrafluoroborate-selective chemical sensor that has better selectivity and other analytical and metrological characteristics compared to global peers. The task has been achieved in such a way that its manufacture used electrode active substance - ion associate 2- (N-ethylcarbazole-3) 1,3,3-ethynyl -trimetil- 3H-indole tetrafluoroborate (EKTI) and a polymeric plasticizer followed material component ratio: EKTI (0.5-8%), plasticizer (44-77%), the rest - the polymeric material. Developed by existing experimental models of chemical sensors that are embedded in the chemical analytical laboratory of JSC "Ukrprofzdravnitsa." Developed sensor is used to determine the mineral boron and hydrothermal waters of the Transcarpathian region.
