| titleOfInvention | A cigarette tar extract with chemiluminescence properties and its chemiluminescence system |
| abstract | The invention discloses a cigarette tar extract with chemiluminescence properties and a chemiluminescence system thereof. The preparation method of the cigarette tar extract includes the following steps: adding the cigarette tar into a reagent for extraction to obtain the cigarette tar extract. The cigarette tar extract of the present invention is prepared by ultrasonic extraction in an open system under natural light conditions, so the luminescent substances contained are stable in nature and are insensitive to factors such as illumination, oxygen and temperature; the extract has luminescence on the pH value of the medium. The response range is wide, and the chemiluminescence reaction can occur under acidic, neutral or basic conditions. The raw materials extracted from the cigarette tar of the invention come from a wide range of sources, and the preparation method is simple. The cigarette tar extract of the invention has wide application prospects in the technical field of chemiluminescence analysis and detection. |
