摘要：

This paper describes the implementation of chemiluminescence detection in an unsegmented continuous-flow system by using a detection cell comprising a rotating disk reactor. Rotation introduces convectional movement and facilitates reaction with concomitant enhancement of the chemiluminescence signal. The rotating disk reactor can also be used as a carrier for immobilized rate modifier (catalyst or promoter) of the luminescence reaction. The overall system has been characterized by means of the luminol-H2O2 reaction with hexacyanoferrate(III) ions and cobalt phthalocyanine as rate modifiers. The versatility of the device for analytical chemiluminescence measurements is illustrated.
