Rapid Identification of Alcohol Compounds by Cyclic Chemiluminescence
摘要
Abstract
Rapid discrimination of compounds with similar structures and properties is a hot topic in analytical chemistry. In this study, a cyclic chemiluminescence (CCL) system was designed by using nano-magnesium oxide as catalyst. The effects of reactant concentration, reaction temperature and detection wavelength on CCL analysis were studied. It was found that the CCL signal satisfied the first order exponential decay law. Each reaction had an exponential decay equation (EDE) describing its signal change law. The initial variable A was proportional to the reactant concentration. The decay-coefficient k was a characteristic constant that was independent of the reactant concentration. For iso-butanol, it's A-values versus concentration was linear in 0. 89-14. 24 mg / L, the average of k-value in this range was 32. 0 with a RSD of 2. 2% . Thus, qualitative and quantitative analysis could be conducted according to the A and k values. The system was used to analyze eight kinds of alcohol compounds, and it was found that there were significant differences in the k-values for different alcohols. For example, the k-values for n-butanol, iso-butanol and sec-butanol were 27. 2 ±0. 2, 32. 0±0. 8 and 19. 5±0. 1, respectively.关键词
