The quenching effect of triethylamine on strong chemiluminescence of bis-(2,4,6-trichlorophenyl)oxalate-hydrogen peroxide system in the presence of 7-amino-4-trifluoromethylcumarin was studied. The system resulted in a nice Stern-Volmer plot with a kQ value of 1.07 x 10(-3) M(-1), in the quencher concentration range of 1.52 x 10(-4) - 1.36 x 10(-3) M. The linear correlation between the decay rate constant of the resulting chemiluminescence and the quencher concentration was also investigated.
