Figure 4. Photooxidation ability of the TPP-doped nanofiber textile.

Photodegradation of AMA during 10 min of irradiation of 3 ml of 10⁻⁴ mol l⁻¹ AMA containing a piece of the nanofiber textile doped with TPP (1 cm²). The arrows indicate the course of photooxidation. Irradiation was performed using white light from a stabilized 300 W Xe lamp with an optical cut-off filter (λ≥400 nm) at 22°C in air-saturated 0.02 mol l⁻¹ phosphate buffer, pH = 7.0.
