Nonlinear Modelling of Kinetic Data Obtained from Photocatalytic Mineralisation of 2,4-Dichlorophenol on a Titanium Dioxide Membrane
Figure 2
Kinetics of disappearance of total
organic carbon (TOC) from 2,4-dichlorophenol (DCP) aqueous solutions. TOC is
expressed as concentration, in mg/L (ppm; mass/volume) of carbon, which was not mineralised, as a function
of time t, expressed in min. Absorbed
radiation power per unit membrane length was 1.50 Wcm-1 during these
runs. In the laboratory-scale photoreactor (see Experimental) standard
photocatalytic membranes, immobilising 30 wt.% of P-15 titanium dioxide, were
employed. In the Figure the four optimised parameters, and , and , obtained by
kinetic modelling, are also reported for this series of runs, together with the
probable error, shown between parentheses, as uncertainty in the last digit.
