Abstract: Glucose carbon microspheres have good adsorption capacity, but it is difficult to be reclaimed in the application. To resolve this problem, a novel composite polyester fiber with carbon microspheres was prepared by one-step hydrothermal carbonization using polyester fiber and glucose as raw materials, acrylic acid as cross-linking agent. The morphology and physicochemical structure of the composite fiber structure were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), respectively. The results showed that a large number of glucose carbon microspheres were dispersed on the surface of polyester fiber uniformly with the particle size of 0.5—1.5 μm. Boehm titration result showed the total amount of surface acidic groups of GC@PFs were 1.95 mmol·g-1, and the isoelectric point (pHpzc), measured by Zeta potential, was about 3.6. Under the condition of 20 ℃, pH=6.3, the maximum theoretical adsorption capacity of GC@PFs to Pb2+ was 20.2 mg/g. The adsorption process could be well described by pseudo-second-order model and Freundlich adsorption model.
