Steps:

2.2. Photochemical and adsorption experiments
The stock solution of aqueous PCP (0.075 mM) was prepared as previously reported [2]. In photochemical experiments, the initial PCP concentration was 0.0375 mM with the dosage of 0.4 g L^-¹ of γ-Fe₂O₃ and the reaction temperature was performed at 30 °C in all photodegradation experiments. The NaOH or HClO₄ was used to adjust the initial pH of suspensions. The photochemical reactor system and the procedure of photochemical experiments were described in detail previously [3]. An 8 W LZC-UV lamp (Luzchem Research, Inc.) with the main emission at 350 nm and a light intensity of 1.2 mW cm^-² was used as a UV light source. Samples were withdrawn at specific time intervals and analyzed immediately after centrifugation at 4500 rpm for 25 min.
