Preparation of New Carbonized Polymer Dots with Folic Acid and Detection of Copper Ion

Fluorescent detection is a practical kind of methods to use in heavy metal ions detection technology. Carbonized Polymer Dots (CPDs) is good carbon-like material with low toxicity, green, ion-response. In this work, we successfully synthesized a yellowing fluorescent CPDs from folic acid. The luminescence intensity of CPDs decreased with the increase of copper ion content, and the detection limit was 0.44ppm.
