Abstract The synthesis of iodo{2,2′-[1,2-octadecanediylbis(nitrilomethylidyne)]diphenolato}cobalt is described. Liquid membrane microelectrodes based on this carrier exhibit Nernstian behaviour with a selectivity sequence according to the Hofmeister series: I– 〉 NO3 – 〉 NO2 – 〉 Cl– 〉 HCO3 – 〉 AcO–. The selectivity coefficient of nitrate over nitrite and chloride amounts to –1.6 and –2.7, respectively. The detection limit for nitrate in water amounts to 10–5.2 mol/L. A nitrate profile measured in a nitrifying biofilm is presented as a practical application.
