摘要：
The effect of the steric accessibility of the exchange center of higher quaternary ammonium salts and plasticizer nature on the selectivity and the limit of detection for film electrodes reversible to hydrophilic double-charged anions was studied. It was established the decrease in selectivity coefficients lgK(i,j)(Pot) by 2.8-3.8 order of magnitude and low detection limit by 2-3 order of magnitude in the series of QAS: TOD <= TC<TL<TNODA<TB<TE<TM<DCPBTM. Also, the increase in low detection limit by 1-0.7 order of magnitude in the series of plasticizers: DBP>DDP>o-NPDE>1-BN was established. The composition of membranes of ion-selective electrodes was optimized.
