Luminol is one of the most commonly used chemiluminescence reagents. It can react with a variety of oxidants and has a high luminescence quantum yield and good water solubility. Luminol chemiluminescence system is widely used in many fields such as chemistry, pharmacy, environmental science, food science and clinical medicine. In luminol chemiluminescence system, the most commonly used oxidant is hydrogen peroxide, but hydrogen peroxide is unstable. The chemiluminescence reaction with luminol is slow and the luminescence intensity is low.
To solve this problem, researchers have developed some novel and efficient luminol chemiluminescence systems without hydrogen peroxide.
Researchers such as Xu Baoguo, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, mixed luminol, thiourea dioxide and a solvent to prepare a luminol-thiourea dioxide chemiluminescence system, in which thiourea dioxide and luminol can be produced by reaction Chemiluminescence, thiourea dioxide has good thermal stability, is safe and non-toxic, has no pollution during production and use, has a fast chemiluminescence reaction with luminol, and has high luminous intensity. Compared with the luminol-hydrogen peroxide chemiluminescence system, the maximum luminescence intensity of the luminol-thiourea dioxide chemiluminescence system is increased by 20 times.
Liu Wei of Shaanxi Normal University and others used Co Fe PBA NAFSs aqueous solution, luminol working fluid and paper matrix containing hydrophilic and hydrophobic regions to form a new type of luminol chemiluminescence system, in which Co Fe PBA NAFSs is anisotropic KCoFe self-assembled nanoparticles with cubic frame structure. In this chemiluminescence system, Co-Fe PBA NAFSs can catalyze luminol to produce strong chemiluminescence on the paper substrate. Co-Fe PBA NAFSs act as a catalyst and sensitizer. It can catalyze luminol to produce strong chemiluminescence, and it only takes about 3.7 seconds from the contact of luminol with Co-Fe PBA NAFSs solution to the maximum absorption peak. , The reaction rate is sensitive and fast.
Because of its simple structure and easy synthesis, luminol is widely used as a luminescence reagent for various chemiluminescence analysis and detection. With the development and update of chemical analysis technology, more novel and efficient luminol chemiluminescence systems will emerge in the future.
