1, 4-Dihydroxyanthraquinone (Quinizarin) in tetrahydrofurane reacts as a novel chemiluminescence reagent in a peroxyoxalate - System

Abdollah Yari, Marzieh Saidikhah

In thiswork,we investigated the chemiluminescence generated fromthe reaction of bis(2,4,6-trichlorophenyl)oxalate (TCPO), hydrogen peroxide and 1,4- dihydroxyanthraquinone (quinizarin). Furthermore, the effect of solvent and concentrations of necessary reagents, TCPO, sodium salicylate, hydrogen peroxide and quinizarin on the luminescence efficiency of the system were studied. Under the optimal condition the suitable values of concentrations of the TCPO:H2O2:SS:Qz systemwere of 5.50 × 10-4, 8.34 × 10-2, 4.27 × 10-6 and 7.51 × 10-4M, respectively.
