Abstract

The invention discloses a method for preparing a poly (benzanthrone) fluorescent molecular sensor for detecting Pd <2+>, which comprises the steps of: taking commercially-available benzanthrone, boron trifluoride diethyl ether and acetonitrile as raw materials, electrochemically synthesizing poly (benzanthrone) in one step in a three-electrode system through constant-potential polymerization, pretreating and dedoping the obtained poly (benzanthrone) and obtaining a polymer, wherein the obtained polymer has better alcohol solubility and good fluorescence characteristic and the Pd <2+> has good fluorescence quenching effect on the polymer, so that the efficient, sensitive and selective fluorescence detection of the Pd <2+> can be realized. The poly (benzanthrone) fluorescent molecular sensor prepared by adopting the method disclosed by the invention has the advantages of low cost, simpleness in process, simpleness and convenience for operation and the like, can be successfully applied to the detection of the Pd <2+> in crops and environments and has good potential practical value and commercial prospect.

Description

technical field

[0001] The invention belongs to the field of fluorescent chemical sensors and relates to a method for detecting Pd 2+ Preparation method of polybenzoxanthrone fluorescent molecular sensor. Background technique

[0002] Palladium has a wide range of uses as a transition metal, such as in the electrical and electronic industries, oral appliances, medical equipment, fuel cells, jewelry and as a catalyst in hydrodehydrogenation reactions. With the development of enterprises, cities, and agricultural modernization, palladium ions cause serious damage to soil and water quality, resulting in high residues in crops and the environment, which have adverse effects on our health, so it has attracted great attention . The government has very strict restrictions on the content of this residual heavy metal in end products. The maximum palladium content allowed in medicines is 5-10ppm, and it is proposed that the maximum palladium intake per person per day should be less...
