Abstract: Microplastic pollution has become a global environmental issue, and transforming it into carbon quantum dots (CQDs) offers an innovative approach to pollution control. In this experiment, CQDs were synthesized using hydrothermal and calcination methods, and their optical properties were systematically analyzed. Additionally, the effect of Fe3+ on the fluorescence properties of the CQDs was investigated. The experiment covers the preparation, performance analysis, and Fe3+ detection, with a simple and practical procedure. It integrates organic chemistry and environmental chemistry, enhancing the experiment’s engagement and educational value, helping students better understand and apply theoretical knowledge while fostering innovation and practical skills.
