Dependence of the degradation of (a,c) phenol and (b,d) its TOC on reaction time in high-activity filtrates or suspensions with different storage times, where the test temperature is 45 °C, C_Phenol = 10 mg L^–1. The “filtrate” was prepared by the reaction of 7.29 μm Al + acid + H₂O₂ in aqueous solution and then filtration. “4.0 g L^–1 7.29 μm Al” represents the suspension of 7.29 μm Al + acid + H₂O₂ with pH = 1.0 and C_Al = 4 g L^–1. “0.04 g L^–1 Al” and “0.1 g L^–1 Al” represent the suspensions of 100 nm Al + acid + H₂O₂ at pH = 3.5 with C_Al = 0.04 and 0.1 g L^–1, respectively.
