Figure 7.
Degradation of 4-NP under different experimental conditions: (a) light; without H2O2; (b) dark; with H2O2 (10 mM) (1.0 g/L catalyst, pH 3); the corresponding logarithmic curves for the determination of rate constants, (c) from (a), (d) from (b). The average error of the values in the kinetic plots is less than 8%.
