Problems solved by technology

Chemiluminescence probes are the core elements of chemiluminescence analysis technology, but existing luminescence probes often have the following deficiencies: (1) the limited number makes it difficult to construct new luminescence systems around existing luminescence probes for analysis and detection; ( 2) Most of the existing luminescent probes are unstable in nature, and are easily affected by external conditions such as oxygen, light and temperature when used; (3) The luminescent reaction of the probe is strongly dependent on the pH value of the system
For example, the chemiluminescent reaction of some luminescent probes can only occur in an alkaline environment, but it is difficult to carry out under neutral and acidic conditions, thus limiting its application in neutral and acidic systems

Abstract

The invention discloses a cigarette tar extract with chemiluminescent properties and a chemiluminescent system thereof. A method of preparing the cigarette tar extract comprises the following steps: the cigarette tar is added to a reagent for extraction, and the cigarette tar extract is obtained. The cigarette tar extract is prepared in an open system under a natural light condition through ultrasonic extraction, the contained luminescent material has stable properties and is insensitive to light, oxygen, temperature and other factors. The extract has a wide luminescent response range for thepH value of a medium, and chemiluminescent reactions can occur under acidic, neutral or alkaline conditions. The raw material for extracting cigarette tar has a wide source, and the preparation methodis simple. The cigarette tar extract has a broad application prospect in the technical field of chemiluminescent analysis and detection.

Description

technical field [0001] The invention relates to chemiluminescence substances, in particular to a cigarette tar extract with chemiluminescence properties and a chemiluminescence system thereof, belonging to the technical field of chemiluminescence analysis and detection. Background technique [0002] Chemiluminescence refers to a light radiation phenomenon produced when a reaction intermediate or reaction product in an electronically excited state absorbs the chemical energy released by the reaction in a chemical reaction and migrates from the excited state to the ground state. Chemiluminescence is an excellent analysis and detection technology with the advantages of mild reaction conditions, simple equipment, convenient operation, and high sensitivity. It is widely used in environmental monitoring, drug analysis, food inspection, bioanalysis, and clinical medicine. However, with the continuous improvement of public health and safety awareness, the analysis requirements in va...
