A copper oxide/carbon nanotube/carbon nitride electrochemical sensor for detecting paracetamol and its preparation method and application

Abstract

A copper oxide / carbon nanotube / carbon nitride electrochemical sensor for detecting acetaminophen, a preparation method therefor and an application thereof. The method comprises: mixing carboxylated carbon nanotubes, carbon nitride, and water uniformly, and performing sonication; then adding copper acetate, mixing uniformly, and performing sonication; and drying after the sonication, and then calcining in an inert gas atmosphere to obtain a copper oxide / carbon nanotube / carbon nitride composite material. A CuO / CNT / g-C3N4 composite modified electrode is prepared and used as an electrochemical sensor for detecting acetaminophen. The electrochemical result shows that the composite material has a good detection effect on acetaminophen.

Description

technical field

[0001] The disclosure belongs to the field of electrochemical analysis and detection, and in particular relates to a copper oxide / carbon nanotube / carbon nitride electrochemical sensor for detecting acetaminophen and its preparation method and application. Background technique

[0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

[0003] Acetaminophen (N-acetyl-P-aminophenol or acetaminophen) is one of the most commonly used pain relievers and is widely used to relieve fever, cold, cough and pain such as headache, toothache and back pain etc. disease. Acetaminophen does not appear to have any serious side effects when consumed in prescribed doses. However, excessive use of acetaminophen can lead to the accumulation of toxic metabolites, which may lead to hepatotoxicity and nephrotoxicity, which in turn damage organs such as the liver and kidneys. Therefore, rapid...
