Simultaneous Adsorption and Photocatalytic Degradation of Malachite Green Using Electrospun P(3HB)-TiO₂ Nanocomposite Fibers and Films

Table 1

Energy dispersive X-ray (EDX) analysis on electrospun P(3HB)-50 wt% TiO₂ and cast P(3HB)-50 wt% TiO₂ composite films after usage in ten repeated decolorization experiments.

	Electrospun P(3HB)-50 wt%				Cast P(3HB)-50 wt%
Element	TiO2 nanofibrous film				TiO2 composite film
	Weight of element (g)
	Before	After	𝑃 * value	% of decrease	Before	After	𝑃 * value	% of decrease
Titanium	0.0737	0.0724	>0.05	1.76	0.0731	0.0491	<0.05	32.83
Oxygen	0.0884	0.0646	<0.05	26.92	0.0866	0.0437	<0.05	49.54
Carbon	0.0516	0.0109	<0.05	78.88	0.0506	0.0112	<0.05	77.87

*Note: the significance of the difference of every element before and after repeated decolorization experiments were analyzed using one-way ANOVA at 95% confidence level.
