| Abstract: | PVC membrane rubidium ion electrodes with valinomycin as neutral ionophore was prepared and its selective coefficient K~(pot)_(Rb,K)=0.35.Determination of rubidium in some aqueous samples by the potentiometric method,known dilution-standard addition and potentiometric precipitation titration has been developed.The activity coefficients for RbCl and Rb_2SO_4 aqueous and nonaqueous(MeOH+H_2O)mixtures were determined by electromotive force measurements with the electrodes. |
