UV Photocatalytic Digestion Utilizing TiO2 Nano-Fiber for the Determination of Total Phosphorus

Abstract:

This paper describes the fabrication, characterization and the application of the photocatalytic TiO2 nanofiber as the photocatalyst for the digestion of total phosphorus (TP). The nanoTiO2 fibers were fabricated by the electro-spinning technique on silicon substrate. Under the conditions of room temperature (25 degrees Celsius) and humidity less than 40%, the TiO2 fabricated by the electro-spinning presents a silky coagulation appearance, which can be converted to the nanofiber appearance by annealed in the muffle furnace at 450 degrees Celsius for 10 hours. X-ray diffraction (XRD) examination shows that the silky coagulation can be converted to anatase-type TiO2. The absorbance values of different phosphate concentrations after exposure in UV light at the intensity of 7000μW/cm2 were tested in this paper. Sodium tripolyphosphate solutions serve as the water sample of TP, and five standard concentrations (by weight of P) are 0.0mg/L, 1.0mg/L, 2.0mg/L,3.0mg/L and 4.0mg/L, respectively. The digestion rate exhibits satisfied linearity ranges from 0.0mg/L to 4.0mg/L with acceptable linearity R2 of calibration curve, in both digestion temperature of 25 degrees Celsius and 50 degrees Celsius.
