3.2.3. Effect of TiO2 concentration on the removal of TC
Fig. 8 showed the effect of TiO2 concentration on the removal of
TC in the reaction system. It was evidently observed that with the
addition of suspended TiO2 (0.5 g L1), the TC removal rate was not
remarkable, which just increased 3.7% in 24 min, compared with
no catalyst of 61.9%. While the TC degradation rate could increase
to 77.9% with the concentration of 1.0 g L1 TiO2, which was higher
than that of 0.5 g L1 TiO2, but less than that to 80.1% of 1.5 g L1
TiO2. It was indicated that photocatalyst assisted corona discharge
plasma system had strength to offer numerous active surfaces by
absorbing lights source, and subsequently react with pollutants
[29]. However, the TiO2 catalyst with a lower concentration would
restrict to connect with UV light and electric field in the system,
which led to fewer chemically active species generation for TC
degradation. A sufficient number of TiO2 could not only motivate
the formation of electric field channel and infiltration of optical
radiation but also enhance the quantum effect of the TiO2 catalyst,
which could response a synergistic degradation of organic compounds
in water effectively
