Abstract (en)
[origin: WO02099409A1] An apparatus and method for determining the presence and/or the concentration of nitrate ions is disclosed. The apparatus includes an ion selective electrode coated with a macrocyclic free base such as 1,7,11,17-tetraoxa-2,6,12,16-tetraazacyclolicosane (RN=235092-95-2) or 1,6,10,15-tetraoxa-2,5,11,14-tetraazacyclooctodecane (RN=236104-63-5). The apparatus can determine the presence of nitrate at low concentrations and has good selectivity towards nitrate ions when in the presence of certain other ions. The invention also provides a method and apparatus for determining the presence and/or concentration of salicylate and periodate ions.
