2.2. Equipment and procedures
Fig. 1 shows the sketch of the 400-mL undivided cell with two-electrode and VX689 magnetic stirring bar. The anode was a 6.5 cm × 7.0 cm RuO2/Ti mesh and the cathode was ACF felt coated RuO2/Ti mesh with the same area as the anode. The DC power was provided by a power supply (DH1718E-4, Dahua Instrument Co., Beijing). The synthetic wastewater was consisted of a predetermined amount of glyphosate in 0.1-M Na2SO4 supporting electrolyte. Unless otherwise specified, pure O2 was fed into the solution at 100 mL/min. At given times, samples were taken and filtrated through 0.45-μm membrane for the analysis of residual glyphosate. The pH of the reaction solution was adjusted by 0.1 M NaOH and H2SO4 solutions.
