The apparent rate constant (kapp in L min–1 g–1) versus pH and the molar ratio of consumed PMS to removed PhOH for (A) CuO, (B) NiO, and (C) Co3O4 is shown here for mean values and error bars. Error bars indicate the standard deviation of duplicate measurements (n = 2). Shaded regions represent confidence intervals (95%). Experimental conditions: [PMS] = 0.3 mM, [PhOH] = 0.15 mM, catalyst = 0.2 g L–1, T = 25 ± 2 °C, 0.2 M borate or glycine buffer.
