How long is the Lumino luminescence reaction

 

Luminol is a chemical reagent that often appears in criminal investigation films, used to detect bloodstains at crime scenes, and the detection process does not cause damage to the DNA in the bloodstains. It is a good helper in restoring the truth of the case. When used, it is mixed with hydrogen peroxide in a certain proportion to form a solution. When sprayed on bloodstained areas, it will emit bright blue fluorescence. It should be noted that Luminol has strong corrosiveness and can cause certain irritation to the skin, eyes, respiratory tract, etc. Direct contact should be avoided as much as possible.

 

In general, the chemical reaction between luminol and hydrogen peroxide is very slow, but with the addition of some catalysts, a rapid luminescence reaction occurs and the luminescence intensity increases. Commonly used oxidants include hydrogen peroxide, potassium persulfate, etc; Commonly used catalysts include metal ions, metal complexes, hemoglobin, etc. This reaction can also be used to detect and analyze organic compounds containing metal ions.

 

When Lumino encounters bloodstains and produces bright blue fluorescence, hydrogen peroxide acts as an oxide, while iron ions and hemoglobin in the blood act as catalysts, causing the bloodstains to quickly emit light. The entire luminescence process lasts for about 30 seconds. In general, there are many factors that affect the luminescence of luminol, such as strong alkalinity, high concentration of alkali, or high concentration of hydrogen peroxide, which can quickly shorten its luminescence process.

 

Therefore, in order to prolong the luminol luminescence reaction time, the above influencing factors can be optimized to delay the luminescence process, which can make the entire luminescence process last for 5-10 minutes, making it more convenient to observe and take relevant photos. Luminol's luminescence reaction is more effective in dark environments, making it easier to observe the luminescence situation.
