A Sensitive Chemiluminescence Method for Determination of Hydroquinone and Catechol

A novel flow-injection chemiluminescence (CL) method has been developed for the determination of hydroquinone (HQ) and catechol (CT), based on their inhibition of the chemiluminescence reaction of luminol–KMnO(4)–β-cyclodextrin (β-CD). It was found that β-cyclodextrin could effectively enhance the c...

description A novel flow-injection chemiluminescence (CL) method has been developed for the determination of hydroquinone (HQ) and catechol (CT), based on their inhibition of the chemiluminescence reaction of luminol–KMnO(4)–β-cyclodextrin (β-CD). It was found that β-cyclodextrin could effectively enhance the chemiluminescence produced from the reaction of luminol with KMnO(4) 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 detection limit 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.
