Abstract

The invention discloses a fluorescent probe containing N, N-diethyl paramethylaminophenol and application thereof in the thiophenol detection. The structural formula of the fluorescent probe is as follows: in a phosphate buffered solution with pH value of 7.4, the compound can be in nucleophilic substitution reaction with thiophenol for releasing out the strong fluorescent material 3-(N, N-diethyl)-6-hydroxy-fluorane, so that the reaction system has a strong fluorescent signal at the wavelength of 543 nm; experimental results show that the fluorescent probe is used to detect the thiophenol; the detection limit of the thiophenol is 6.0*10<-9>mol / L; the relative standard deviation is 2.6%; the qualitative and quantitative detection of the thiophenol can be realized. The detecting method is simple in operation, high in accuracy and sensitivity and good in selectivity; different thiol compounds have no disturbance to the system of the fluorescent probe detecting the thiophenol; the fluorescent probe can be used for detecting the content of the thiophenol in a water sample.

Description

technical field

[0001] The invention belongs to the technical field of thiophenol detection, and in particular relates to a fluorescent probe containing N,N-diethyl-p-rhodol and a method for measuring thiophenol with the fluorescent probe by means of fluorescence photometry. Background technique

[0002] Thiophenol is a colorless liquid with a special odor and is not easily soluble in water. It is an important reaction intermediate in organic synthesis and can be used to synthesize various drugs, catalysts, polymerization inhibitors, fuels, etc., such as the production of medicine chloramphenicol Thiamphenicol, local anesthetics, pesticide Kewensan, rubber regeneration agent, petroleum additives, etc. Thiophenol has a strong irritating effect on the eyes, mucous membranes, respiratory tract and skin. It is easy to cause poisoning after inhalation, with symptoms such as burning sensation, coughing, wheezing, nausea, and vomiting. It is transmitted to the kidneys and liver thr...
