in which c is the concentration of reactants; t is reaction
time; k is the rate constant, K is the adsorption constant.
The kinetic parameter of k and K are affected by
light intensity, temperature, the initial concentration
and physical properties of reactants, the gaseous oxygen
concentration, etc. In liquid phase reaction system,
the initial value of pH is another factor. In suspension
system, the geometry and the experiential parameters
of the reactors should also be considered [17]
