A Sensitive Chemiluminescence Method for Determination of Hydroquinone and Catechol

Abstract

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.

Electrochemical study for the simultaneous determination of phenolic compounds and emerging pollutant using an electroanalytical sensing system based on carbon nanotubes/surfactant and multivariate approach in the optimization

“…Although target compounds were not found in the water samples, it is important to note that some studies have reported the determination of HQ [45], CT [45,46], and p-NP [43] in water samples in concentrations HQ -hydroquinone; CT -catechol; AC -acetaminophen; p-NP -4-nitrophenol; LOD -limit of detection; LOQ -limit of quantification; DPV -differential pulse voltammetry; SWV -square wave voltammetry.…”

A New Catechol Biosensor Immobilized Polyphenol Oxidase by Combining Electropolymerization and Cross-Linking Process

“…Thus, it is crucial to develop a rapid and effective detection method for catechol. Current methods for catechol detection include spectrophotometry, capillary electrophoresis [2], voltammetry [3,4], chromatography [1], and chemiluminescence (CL) [5,6]. However, these methods have disadvantages, such as high cost, time-consuming, and low sensitivity, and they sometimes require complicated sample pretreatment (i.e., preconcentration or extraction) that limited their application.…”

Laccase Biosensor Based on Graphene-Chitosan Composite Film for Determination of Hydroquinone

“…This chemical is harmful to humans and the environment, and therefore it is necessary to develop a fast, easy, and accurate detection method. From the literature, several methods for the determination of hydroquinone are available, such as high-performance liquid chromatography (Lin et al 2005), spectrophotometry (Sirajuddin et al 2007;Zeng et al 2007), chemiluminescence (Zhao et al 2007), and electrochemical biosensors. Among them, biosensors are of considerable interest due to the advantages of easy operation and rapid analysis.…”
