Abstract

The disclosure provides a carbon quantum dot hydrogel, a preparation method thereof, and a method for detecting copper ions. The carbon quantum dot hydrogel includes carbon quantum dots and agarose hydrogel. The carbon quantum dots are bonded in the network structure of the agarose hydrogel.

Description

technical field [0001] The disclosure relates to the technical field of nanomaterials, in particular to a carbon quantum dot hydrogel, a preparation method thereof, and a method for detecting copper ions. Background technique [0002] Copper is an important element of life. The content of copper in the human body is second only to zinc and iron. Copper plays an important role in human biosynthesis and metabolism. However, excessive copper ion content in the human body can easily induce neurological diseases. Furthermore, copper is a heavy metal element and one of the most common harmful metal elements in sewage. Copper ions cannot be biodegraded and are likely to cause lethal harm to algae and other aquatic organic life forms. Moreover, the food chain will cause enrichment and amplification of copper ions. Therefore, controlling the copper content in water is very important for protecting the environment and promoting human health. At present, copper ion detection meth...
