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 W cm-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.
