Abstract:
This work demonstrates for the first time the electrochemiluminescence (ECL) of luminol on a Ti/TiO(2) NT electrode and its analytical application for the detection of pentachlorophenol (PCP). Luminol emits stable and intensive light on the Ti/TiO(2) NT electrode at -0.6 V, and PCP is found to be able to inhibit the ECL intensity. PCP is detected based on the inhibition of ECL intensity. The proposed method exhibits good reproducibility, wide-range linearity (0.3 pM to 3 μM), and high sensitivity with a limit of detection (LOD) of 0.1 pM (S/N = 3). The possible inhibition mechanism has also been discussed.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
