A Cd2+ selective electrode Crytur 48-17 proved to serve well for the titrimetric determination of some types of organic reagents, particularly of 8-hydroxyquinoline and its derivatives, sodium N,N-diethyldithiocarbaminate, pyridylazo dyes (PAN, PAR), and aminocarboxylic acids (NTA, EDTA, DCTA) with 0.01M cadmium nitrate solution in the medium of ammoniacal or borate buffers. The titrimetric determinations examined can be classified as precise analytical methods.
