    Ouwen XU, Wei LIU, Jiawei LI, Shuyu WAN, Xiashi ZHU. A Novel Surfactant Sensitized Fluorescent Sensor for Co(II) Based on Nitrogen Doped Carbon Quantum Dots[J]. Photonic Sensors, 2022, 12(2): 152 Copy Citation Text show less


    A novel nitrogen-doped carbon quantum dots (N-CDs) were prepared by the microwave irradiation method. The fluorescence quenching effect of Co(II) on the N-CDs was studied in the sodium dodecyl sulfate (SDS) medium and the fluorescence quenching was sensitized in the SDS. The linear range of calibration curve for the determination of Co(II) was 0.17 μg/mL–11.8 μg/mL and the limit of detection was 0.052 μg/mL. The method has been applied for the determination of Co(II) in samples with satisfactory results.
