Effect of deputy group metal ions on the fluorescent properties of the CPPO-H_2O_2-Rhodamine B system

摘要

The influence of metal ions on the peroxyoxalate chemiluminescence reaction was investigated. A number of metal ions showed the quenching effect of the chemiluminescence reaction of bis (3, 5, 6- trichloro-2-carbopentyloxy) oxalate with hydrogen peroxide in the presence of Rhodamine B as the fluorophore. Copper ion gave the highest quenching effect. The reason for the decrease in the chemiluminescence intensity by metal ions is probably a change in the conjugative structure of Rhodamine B due to combination of metal ions and Rhodamine B.
