Abstract: A novel flow-injection chemiluminescence(CL)method has been developedfor the determination of hydroquinone (HQ) and catechol (CT), based on their inhibition ofthe chemiluminescence reaction of luminol–KMnO4–β-cyclodextrin (β-CD). It was foundthat β-cyclodextrin could effectively enhance the chemiluminescence produced from thereaction of luminol with KMnO4 in basic media. The proposed method is simple, rapid,convenient and sensitive, has a linear range of 1–20 ng/mL for catechol with a detectionlimit of 0.4 ng/mL, and 1–10 ng/mL for hydroquinone with a detection limit of 0.1 ng/mL,respectively. The possible mechanism of the CL reaction is also discussed
