The results illustrated in Fig. 5(a) indicated that TOC reduced
with increasing treatment time and TOC abatementswere not very
different from each other for all initial pH values for 120 min of EC
operation. At the end of EC operation, the highest TOC removal efficiency
(50%) together with the highest reaction ratewere observed
for EC started at an initial pH of 6 and resulting in a remaining
TOC of 85mg/L.
