Purpose of the development: The method used for determining the concentration of boron and is used for control of the environment, food analysis, biologically active compounds and drugs. Boron is a common element in hydrothermal, marine, drinking and waste water, glass, food. It is important in steel production, where the concentration of boron in the metal is affected by the mechanical and operational characteristics of the finished product. Boron is an effective absorber of neutrons, so the water with elevated levels of this element is used as a means of safety at nuclear power plants. The biological role of boron as a trace element remains poorly understood.

Recommended application field: Analytical Chemistry. Can be used in the factory, research, and chemical analytical laboratories.

Advantages over analogues: In the country there is no analogous ionometric methods for determining boron. Compared with foreign counterparts, the developed method allows to analyze by 30-40 minutes instead of 1-2 hours, do not use special boron-specific resin, which significantly reduces sample preparation for analysis, not to apply in the preparation of samples concentrated aggressive acids, and in general, cheaper cost of the analysis without loss of accuracy results. Durability of the sensor, created by the developed method, is 24 months instead of 18 for a foreign counterpart.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
The invention relates to analytical chemistry, namely ionometry. Unlike other methods of analysis which allow to determine only the total concentration of substances ionometry allows us to estimate the activity of free ions. Method of determination of boron , including replace of boron compounds in the form of tetrafluoroborate ions with acidic solutions with ftorid and the measurement of ion activity tetrafluoroborate using a chemical sensor, which is characterized by the fact that as an elektroactive matter of chemical sensor using ionic associate 2 - (N-3-etilkarbazol )-ethynyl-1,3,3-trimethyl-3H-indole tetrafluoroborate with the ratio of the components: 1.2% - 2 - (N-etilkarbazol-3)-ethynyl-1,3,3-trimethyl-3H-indoles tetrafluoroborate, 65.8% - about nitrofeniloktilovy-ether, The rest - polyvinyl chloride.
