Abstract

The invention discloses polyimide containing porphyrin as well as a preparation method and application thereof. Soluble polyimide containing the porphyrin is synthetized through condensation reaction on a diamino tetraphenyl porphyrin monomer, an aromatic organic diamine monomer and an aromatic dianhydride monomer, and a polyimide nano-fiber film containing the porphyrin is prepared by further applying an electrostatic spinning technology. The method has the advantages of simple operation, strong controllability, high repeatability and recyclable product. The polyimide nano-fiber film containing the porphyrin is applied to the detection of heavy metal mercury ions in a water solution and has the advantages of high sensitivity, good selectivity and rapid response.

Description

technical field

[0001] The present invention relates to a porphyrin-functionalized polymer compound, in particular to a porphyrin-containing polyimide and a preparation method thereof, and a preparation method of a porphyrin-containing polyimide nanofiber membrane and its presence in trace amounts of mercury ions. application in detection. Background technique

[0002] As we all know, mercury is a heavy metal that is harmful to human health. It can enter the human body through various channels and accumulate in the body. Inorganic mercury ions in water can be converted into more toxic organic mercury, enter the human body from the food chain, deposit in the brain, liver and other organs, cause chronic poisoning, damage the kidneys, brain, stomach and intestinal tract, and even cause death. For the above reasons, the detection of mercury in the environment has attracted great attention. A lot of work has been done on mercury detection methods, among which the most widely us...
