Abstract: Electrochemical properties of heterogeneous poly(vinyl chloride) membrane containing electrically active caesium cobalt nitrite (Cs3Co(NO2)6.2H2O) and dibutyl phthalate as plasticizer were studied. Slope of the ionic function of the ion-selective electrode made of this membrane was 40-43 mV/pCs. Dependence of EMV on the concentration of caesium ions was found to be linear in the 5 X 10-2 to 10-4 mol dm-3 range. Apparent potentiometric coefficients of selectivity for cations Li+, Na+, K+, Rb+, NH4+, Ag+, Mg2+, Ca2+, Co2+, Ni2+, and Fe3+ were estimated by the separate solutions method. The pH of solutions within 4.5 and 9.5 did not influence the electrode response.
