Hydroxyquinoline disulfide zirconium ion fluorescent probe and preparation method thereof

The preparation method comprises the following steps: carrying out substitution reaction on alpha-bromoacetophenone and ammonium pyrrolidine dithioformate, carrying out acylation reaction on the product and hydrazine hydrate, carrying out amine-aldehyde condensation on the product and 8-hydroxyquinoline-2-formaldehyde, and carrying out column chromatography to obtain the hydroxyquinoline disulfide zirconium ion fluorescent probe. The hydroxyquinoline disulfide zirconium ion fluorescent probe is prepared. The hydroxyquinoline disulfide zirconium ion fluorescent probe disclosed by the invention is simple in preparation and use method, strong in specific recognition, short in response time and wide in pH application range, can recognize strong green light by naked eyes, is beneficial to rapid detection of zirconium ions in a water body and an ecological environment, and has practical application and popularization values. 本发明涉及一种羟基喹啉二硫类锆离子荧光探针及其制备方法，其制备方法是先通过α-溴代苯乙酮与吡咯烷二硫代甲酸铵进行取代反应，产物与水合肼进行酰化反应，然后再与8-羟基喹啉-2-甲醛进行
