Углеродные точки (CDs) без поверхностных функциональных групп синтезированы простым одностадийным гидротермальным методом с использованием 4,4 '-бипиридина в качестве источника углерода. Показано, что синтезированные CDs обладают хорошей селективностью к обнаружению Fe3+ и реагируют на ионы металлов как основания Льюиса. Диапазон обнаружения концентраций Fe3+ от 1.0×10-8 до 1.0×102моль/л, предел обнаружения 1.0×10-8моль/л.

Carbon dots (CDs) are of great significance for metal ion detection. Herein, CDs without surface functional groups were synthesized through a simple one-step hydrothermal method using 4,4 '-bipyridine as the carbon source. The results showed that the synthesized CDs have good selectivity for Fe3+ detection, and the CDs respond well to metal ions as Lewis bases. This detection method is unlikely to be affected by sewage systems because it has excellent sensitivity. The detection range for Fe3+ concentrations is between 1.0×10-8 and 1.0×102 mol/L, and the detection limit is 1.0×10-8 mol/L.
