Webtains NaCl with varying conductivity because it is easily found in water and wastewater. Figure 4 clearly shows that the phenol removal increases as the NaCl concentra- tion of the feed solution raises from 0.5 to 3 g/L. As shown in Figure 4, the efficiency of phenol removal in- creased from 55.5% to 86.6% after 60 min of electroco- agulation.
