Abstract:
Herein, silica nanoparticles were employed as the carrier for surface molecular imprinted polymer with high selectivity for Tetrabromobisphenol A (TBBPA). Nitrogen-doped graphene quantum dots (NGQDs) were incorporated to enhance the chemiluminescence intensity of the Luminol-H2O2 system, as TBBPA was found to effectively suppress the chemiluminescence signal of this system. Based on these principles, a molecular imprinting technique-chemiluminescence (MIT-CL) sensor was developed by integrating the NGQDs-sensitized Luminol-H2O2 chemiluminescence system with the specific recognition material SiO2@TBBPA MIP was constructed to detect TBBPA in environmental water samples. Under the optimal conditions, the sensor exhibited a linear detection range of 8.0 × 10-10-2.0 × 10-8 mol/L, with the detection limit (3σ/k) of 3.2 × 10-11 mol/L. The illustrated MIT-CL method was utilized for the detection of TBBPA in water samples, yielding satisfactory recovery rates ranging from 96.25 % to 107.50 %.
