Current research activity, main achievements
The main scientific works are in the field of ionometry and chemistry of extraction.
The main achievements are as follows:

  • a method for predicting the ion-exchange and ionic associates extraction constants, based on the separate consideration of the extractionparameters of individual ions, determined for standard systems;
  • discovery and theoretical substantiation of the effect of a lipophilic ionic additive on the selectivity of electrodes based on liquid ion exchangers [1], as well as of the effect of strong dependence of potentiometric selectivity on the steric availability of the exchange site [2];
  • the theory of the functioning of H+-selective electrodes based on neutral carriers in strongly associated systems [3, 4];
  • formulation of the main principles and substantiation of specific ways to control the selectivity of ion-selective electrodes, reversible to the cations of physiologically active amines of various structures [5];
  • substantiation of experimental methods for estimation of the diffusion characteristics of membranes of ion-selective electrodes from potentiometric data [6, 7], as well as methods for estimation of the selectivity coefficients of highly selective electrodes [8, 9].

More than 40 ion-selective electrodes with improved performance characteristics, in particular, for determination of pH, sulfate, water hardness, a number of physiologically active amines, non-steroidal analgesics have been developed.
About 400 scientific works, including more than10 reviews and 29 author certificates for inventions and patents were published.
6 Ph.D. dissertations were fulfilled under supervision.
The diplomas of the Ministry of Higher and Secondary Special Education of the BSSR (1982, 1987), the Certificate of Honor of the Ministry of Public Education of the BSSR (1982), the Certificate of Honor of the Ministry of Education of the Republic of Belarus (2003), the sign "Inventor of the USSR".
