A Comparison of PFOA removal efficiency ac, under UV light, indicating an increase in removal efficiency with higher Fe content with [PFOA]0 = 1 mg L−1. B Impact of initial PFOA concentration on its removal using a 32 wt% Fe-doped g-C hybrid photocatalyst, demonstrating decreased removal efficiency with higher concentrations of PFOA. C Removal efficiency of PFOA under dark conditions, UV radiation (254 nm), and simulated solar light (AM 1.5 G), showing the enhanced removal capability under simulated solar light with [PFOA]0 = 1 mg L−1. All experiments were conducted with a photocatalyst dosage = 1 g L−1, temperature = 22 ± 2 °C, and UV fluence rate = 1.42 ± 0.05 mW cm−2. Trend lines are provided to aid visual interpretation of the data.
