Abstract
An investigation was conducted on photocatalytic reduction and physical adsorption of Cd(II) in titania PVA-alginate beads. In order to determine the kinetics of photocatalytic process, the influence of the initial concentration was examined in detail. An exact analysis on the percentage of the initial reduction rate versus time at different initial concentrations of Cd(II) showed that with an increase in the initial concentration, the rate of substrate conversion reduced. It was also revealed that the beads containing the TiO2 nanoparticles can be easily isolated from the aqueous solutions after the sorption process and can be reused for at least six times before it loses its initial properties. The reduction of Cd(II) with titania PVA-alginate beads fitted the pseudo-second-order kinetic model with a correlation coefficient (R2) of 0.9993
