Abstract

Abstract:

In this experiment, carbon dots were prepared by hydrothermal method with citric acid as raw material. The colorimetric detection of Mn²⁺ was realized via the catalytic oxidation discoloration of Mn²⁺ to 3, 3', 5, 5'-tetramethylbenzidine (TMB) in the mixed system of carbon dots and TMB. Selectivity and sensitivity of the detection were studied by UV-Vis absorption spectrum. This comprehensive experiment covers the preparation and characterization of nanomaterials and the analysis and detection to important substances. It not only exercises students' comprehensive ability to use knowledge and experimental skills, but also helps to broaden students' academic vision.

Key words: Carbon dots, 3, 3', 5, 5'-tetramethylbenzidine, Mn²⁺, Colorimetric detection
