3.4. Determination of decolorization kinetics
The decolorization kinetics of RB181 by UV/H2O2 process was
studied for various contact times changing from 0.5 to 30 min. The
data were then regressed for the
first order kinetic (Eq. (7)),
pseudo-first order kinetic (Eq. (8)), second order kinetic (Eq. (9))
and for a pseudo-second-order kinetic equation (Eq. (10)). The
calculated kinetic parameters are presented in Table 3.
