Notizen: The potentiometric selectivities of membranes based on new N, N' -substituted 4, 13-diaza-18-crown-6 ethers were determined under different internal filling electrolytes and conditioning time of the membranes. The preference of Hg2+ over other divalent cations was observed for compounds bearing 2-methylquinolyl or 2-methylquinolyl-1-oxide groups. The membrane electrodes with ionophores 1 and 2 exhibited a linear response in the activity range 10-5 - 10-3 M Hg(NO3)2.
