Description :
In the present work p-amino benzoic acid in its aqueous solution was treated by peroxidation (H2O2),
photo peroxidation (UV/H2O2) and photofenton (UV/Fe2+/H2O2) processes. The experiments were taken
out in a batch photoreactor using 8W low pressure mercury vapor lamp to examine the effects of different
combinations and their degradation rates are compared. Substrate concentration was fixed by utilizing a
UV-Visible spectrophotometer. The results indicated that the rate of degradation follows the following
sequence; photofenton > photoperoxidation > peroxidation. The photo degradation processes were
adhered to first order dynamics.
