Abstract
dc:description.abstractThe detection of copper ions as Cu(dmp)₂⁺ (dmp=2,9 -dimethyl-1,10-phenanthroline) using electrochemiluminescence (ECL) is reported. Cu(dmp)₂⁺ is formed in situ by reducing Cu₂⁺ ions to Cu⁺ with hydroxylamine hydrochloride and then complexing with the chelating agent dump. ECL was generated by oxidizing Cu(dmp)₂⁺ in the presence of tri-n-propylamine (TPA). The ECL intensity peaks at a potential corresponding to oxidation of both TPA an Cu(dmp)₂⁺, indicating that the emission is from a Cu(dmp)₂⁺ metal-to-ligand charge transfer excited state. Conditions for ECL omission were optimized and used to generate a calibration curve that was linear over the 0.1-5 mg/L (ppm) range. The theoretical limit of detection was 6 μg/L (ppb), with a practical limit of detection of 0.1 ppm. The ECL of several metals ions other than copper with dmp and their effects on Cu(dmp)₂⁺ ECL were examined.
