Abstract
This invention provides a method for preparing carbon quantum dots, their application in the detection of 4-nitrophenol and curcumin, a concentration detection method, and a visualization detection method. The method involves mixing tris(hydroxymethyl)aminomethane and phloroglucinol in a solvent, followed by heating in a reaction vessel to obtain the carbon quantum dots. This invention provides a simple and low-cost method for preparing carbon quantum dots, enabling rapid and low-cost detection of 4-NP and curcumin, thus meeting the detection needs for both.
