Zr < 4 + >-induced metal organic gel fluorescent switch sensing material and preparation method and application thereof

Abstract

The invention discloses a Zr < 4 + >-induced metal organic gel fluorescent switch sensing material and a preparation method and application thereof, and the method comprises the following steps: A1, transferring DMF and H2O into a reaction vessel, and then fully shaking until the DMF and H2O are completely mixed, wherein the volume ratio of DMF to H2O is 7: 3; A2, adding BTC into the reaction container, wherein the reaction container is subjected to ultrasonic treatment for 20 seconds until the ligand BTC in the system is completely dissolved, and then adding ZrCl4 into the mixed solvent, wherein the molar ratio of ZrCl4 to BTC is 1: 4; and A3, putting the reaction system into an ultrasonic instrument, and carrying out ultrasonic treatment at 80 DEG C for 30 minutes to form white columnargel. According to the constructed novel fluorescence switch sensing platform, ARG can be selectively detected through a charge transfer effect, and CrO4 < 2-> in water can be rapidly detected and removed through energy resonance transfer and a chemical adsorption effect.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, uses trimesic acid, arginine and zirconium chloride as main raw materials, and uses DMF and H 2 O as a solvent to construct a Zr 4+ Inducible metal-organic hydrogel fluorescent switch sensing platform for stable and selective detection of ARGs and rapid detection and removal of CrO in water 4 2- . Background technique [0002] Arginine (ARG) is a semi-essential basic amino acid containing multiple N-binding sites in the human body, which plays an important role in wound healing, promotion of urea synthesis and excretion, and maintenance of acid-base balance and sperm motility. ARG is usually used in food as a flavoring or nutritional supplement, added to edible products. Although ARG has many benefits to the human body, it is not suitable for people with different constitutions or health levels due to its special requirements for food. For example, people with allergies, diabetes or liver...
