Abstract

The invention relates to a synthesis method and application method of a benzothiazole di-Schiff base fluorescent molecular probe for detection of iron ions. The fluorescent molecular probe is obtainedthrough condensation of benzothiazole-2-formaldehyde and 2-hydroxy-1-naphthylhydrazine, and the fluorescent molecular probe is dissolved in a mixed liquid of dimethyl sulfoxide and an HEPES buffer solution so as to obtain a fluorescent molecular probe solution, wherein the pH value of the HEPES buffer solution is 6-8, and the volume ratio of methyl sulfoxide to the HEPES buffer solution in the mixed liquid is 3:7, and the concentration of the fluorescent molecular probe in the mixed liquid of 3:7 is 7-10 [mu]mol / L; a to-be-detected sample of 20 [mu]mol / L is added to the taken fluorescent molecular probe solution, and even mixing is performed so as to obtain a sample solution. The synthesis method and application method have the advantages that high-selectivity identification of Fe<3+> inthe water environment system can be realized, no interference is caused by other metal ions in the water solution, and a high anti-interference ability is achieved.

Description

technical field

[0001] The present invention relates to Fe 3+ The invention relates to the synthesis and application of a fluorescent molecular probe for detection, in particular to a synthesis and application method of a benzothiazole double Schiff base fluorescent molecular probe for iron ion detection. Background technique

[0002] Iron is not only an element that widely exists in nature, but also one of the important trace elements in living organisms. It plays a key role in many physiological processes. It can not only transport nutrients and oxygen, but also has a very close relationship with the hematopoietic function of the human body. Relationship. It participates in the synthesis of various active enzymes and hemoglobin in cells, and promotes cell growth and metabolism. When the concentration of iron ions in the body is too high or too low, it will disturb the normal activities of the life system and poison the cells, which will lead to metabolic disorders and in...
