Time variation of pH value for decomposition of DMP via WOP at various pressures. ○, △, +, and ×: = 2.41, 2.76, 3.10, and 3.45 MPa. = 100 mg L−1, = 400 mL, = 483 K, and Nr = 500 rpm. Working gas after time = 0f is O2. ↕: Mean and Standard deviation (SD, method) at = 0i: 5.2 ± 0.2 and at = 0f: 4.1 ± 0.2.
