摘　　要：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 pg/mL-11.8 pg/mL and the limit of detection was 0.052 pg/mL.The method has been applied for the determination of Co(II)in samples with satisfactory results.
