摘要:
以柠檬酸为碳源,采用一步熔融法制备了石墨烯量子点,通过红外光谱、紫外-可见吸收光谱、荧光光谱对其光学性能进行表征,同时考察了石墨烯量子点耐光漂白能力和抗盐性. 该石墨烯量子点可应用于对苯二酚的检测,其荧光强度与对苯二酚浓度成良好的线性关系(R2=0.979),方法的检测限为3.1 nmol·L-1, 线性范围为1.0×10-7~5.0×10-6 mol·L-1.
Abstract:
With citric acid as carbon source, graphene quantum dots was prepared by one-step melting method. The spectral properties of the graphene quantum dots was characterized by FTIR, UV-visible absorption spectra and fluorescence spectra. In addition, its ability of light bleaching and salt resistance were investigated. Then, the graphene quantum dots was used for the detection of hydroquinone by a fluorescent sensor. The fluorescence intensity of graphene quantum dots and the concentration of hydroquinone exhibited a good linear relationship(R2=0.979)with a wide concentrations range of 1.0×10-7~5.0×10-6 mol·L-1 as well as the limit of detection was calculated to be 3.1 nmol·L-1.
