- Overview
  - Zincon is a colorimetric reagent for Zn and Cu detection, and a metal indicator in EDTA titration. This reagent is insoluble in organic solvents, but slightly soluble in water and alcohol. Its proton dissociation constants are reported to be pKa1=7.9-8.3, pKa2=7.9-8.3 and pKa3=13-14. The aqueous solution of Zincon is yellow or orange-yellow in weak alkaline conditions, and turns blue in the presence of Cu (maximum wavelength: 600 nm, molar absorptivity: 1.9x104) and Zn (pH 8.5-9.5, maximum wavelength: 620 nm, molar absorptivity: 23,000). Dr. Koupparis and others used Zincon for the automated flow injection spectrometric determination of 1-10 mg per ml levels of Zn at 80 samples per hour. The detection limit was reported to be 0.05 μg per ml.
