| 摘 要： | N-doped peanut membrane carbon quantum dots (N-CQDs) were prepared by one-step hydrothermal method using peanut membrane and urea as materials. On the basis of investigating the spectral characteristics of the N-CQDs, we found that KMnO4 could cause the fluorescence signal of the N-CQDs to "turn-off" in the B-R buffer system with pH 10. 38. Once hydroquinone was added, the fluorescence signal of the N-CQDs-KMnO4 system gradually recovered and the fluorescence signal "turned on". Based on this, a new "off-on" fluorescence probe method for the detection of hydroquinone-N-CQDs-KMnO4 system was developed. Under the optimized conditions, the recovered fluorescence of N-CQDs was linearly related with the hydroquinone concentration in the range of 0. 10-200 mmol / L, the linear equation was ΔF = 1. 6819c + 153. 84 (r = 0. 9992), with the detection limit of 30 μmol / L. The method has been successfully applied to the determination of hydroquinone in simulated samples. © 2022, Youke Publishing Co.,Ltd. All rights reserved.
