Description

Technical field [0001] The invention belongs to the technical field of analysis and detection materials, and specifically relates to an imprinted polymer membrane electrode of p-chloroaniline. The invention also relates to a preparation method of the imprinted polymer membrane electrode of p-chloroaniline and the prepared p-chloroaniline imprinted polymerization A method for detecting p-chloroaniline under a zero current potential system with a film electrode. Background technique [0002] P-Chloroaniline (PCA) is a chlorinated aromatic amine compound, which is the main raw material and intermediate for synthetic rubber, chemical reagents, dyes and other chemical products, as well as medicines and pesticides. PCA is widely distributed and accumulated in farmland soil and industrial wastewater. It is toxic when inhaled or in contact with the skin, and has a cluster of poisoning hazards. Once a person is poisoned, it will cause symptoms such as liver swelling, liver pain, and memor...
