Nanofibrous Mats for Effective Water Treatment
Figure 4
(a) The degradation of 4CP in contact with BFO nanofibers as a result of irradiation by the light with the wavelength of 385 nm. The gradual decrease in the different concentrations (1, 2, 5, and 7.5 μg/mL) of 4CP compared to the insignificant change in concentration for 4CP-blank and 4CP-dark is depicted. The inset illustrates the application of pseudo-first-order kinetics for the degradation of the 4CP, (b) the degradation of 4CP for 4CP-sat sample. The trend shows a stop in the degradation process at 120 min probably due to surface saturation, and it is resumed after the BFO nanofiber mat is rinsed.
