✦ Synopsis

Electrochemiluminescence (ECL) of 200 ppm 2,3-diaminonaphthalene (2,3-DAN) was studied alone and in conjunction with 100 ppm of 34 different metal and non-metal ions and revealed three relatively intense ECL responses from interactions of 2,3-DAN with Au , Fe 3 and V 5 . ECL responses from Cr 6 or Ru 3 with 2,3-DAN were less intense, but noteworthy, as was the coloured ¯uorescent product of the non-metal ion Se 4 interaction with 2,3-DAN. Several intense 2,3-DAN±metal ion ECL reactions were studied in greater detail and revealed various titration curves with ionic detection limits in the low ppm range, using a ®xed level (200 ppm) of 2,3-DAN.
