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.
