Nonlinear Modelling of Kinetic Data Obtained from Photocatalytic Mineralisation of 2,4-Dichlorophenol on a Titanium Dioxide Membrane
Figure 1
Kinetics of disappearance of
2.4-dichlorophenol (DCP), from its aqueous solutions, in a laboratory-scale
photoreactor (see Experimental), with 1.50 Wcm-1 of absorbed
radiation power per unit membrane length, and standard photocatalytic
membranes, immobilising 30 wt.% of P-25 titanium dioxide. Concentrations, C in mg/L (ppm; mass/volume), for DCP,
are expressed as carbon, which was not transformed into intermediates, as a
function of time t, expressed in minutes.
In the figure, the four optimised parameters, and , and , obtained by
kinetic modelling, are also reported, together with the probable error, shown
between parentheses, as uncertainty in the last digit.
