Nonlinear Multicomponent Kinetic Analysis for the Simultaneous Stopped-Flow Determination of Chemiluminescence Enhancers

Protocatechuic and caffeic acids were determined from kinetic data of luminol chemiluminescence induced by hexacyanoferrate(III) enhanced by phenolic acids. The phenolic acids could be quantified both separately and together using the stopped-flow technique and monitoring intensity at 0.3 s and the initial rate. Synergy was observed when two or more enhancers acted simultaneously
