Abstract

The invention provides an anion receptor based on 5-nitrofuran formyl hydrazone and phenolic hydroxyl. The anion receptor is obtained by mixing 2, 6-dimethylacyl-4-chlorophenol and 5-(4-nitro)-phenyl-2-benzoyl diazanyl furan according to certain proportion, stirring and refluxing the mixture for 3 to 8 hours at a temperature of between 70 and 100 DEG C by using anhydrous ethanol as a solvent and p-toluene sulfonic acid as a catalyst, distilling out most of the solvent through reducing the pressure, performing suction filtration after cooling, and performing recrystalization on the solid product by using DMSO-EtOH. The anion receptor has color comparison recognizing ability on fluorion, acetic acid radical and phosphoric acid dihydrogen radical in a DMSO solution. The anion receptor is dissolved in DMF to be prepared into 0.5 to 2.0 percent of solution which is cooled to room temperature to be prepare into stable anion receptor organic gel used for performing colorimetric detection on the fluorion, and the acetic acid radical and phosphoric acid dihydrogen radical ions in the DMSO solution. The anion receptor has the advantages of convenience for carrying, convenient use, high detection sensitivity and the like.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and relates to an anion acceptor based on nitrofuroylhydrazone and phenolic hydroxyl group and a preparation method thereof. The invention also relates to the preparation of the anion acceptor organic gel and its application in anion detection. Background technique

[0002] Anions play a fundamental role in life systems, environmental systems and chemical production. Especially in living systems, anions play an important role in the realization of life processes. Therefore, the detection of anions is a very necessary work. For example, fluoride ion is an anion that has an important impact on living systems. It is well known that the human body can prevent dental caries and prevent osteoporosis by taking an appropriate amount of fluoride ions. However, excessive intake of fluoride ions can lead to fluorosis. Mild fluorosis can harm the ameloblasts of human tooth germs. Severe fluorosi...
