Abstract

The present work deals with the first attempt to study the effect of L-TYROSINE on the characteristics of the peroxyoxalate chemiluminescence. BERBERINE was applied as an efficient fluorophore. The investigated parameters include rise and fall rate constant for the chemiluminescence burst, theoretical and experimental maximum intensity, the time needed to reach maximum intensity and the total light yield emission, which is theoretically evaluated using the pooled intermediate model by a computerized non-linear least-squares curve fitting program (KINFIT). Furthermore, based on the observed QUENCHING effect of tyrosine, the STERN–VOLMER PLOT with KQ value of 7.7×104 M-1 in the quencher concentration range 4×10-6 –5×10-5 M. Moreover, this method is applied to determinate tyrosine in biological samples successfully.
