Photodegradation applied to the treatment of phenol and derived substances catalyzed by TiO/BiPO and biological toxicity analysis.

For this work, a phenol solution model was treated by an advanced oxidation process (AOPs), using the heterogeneous catalyst TiO/BiPO and hydrogen peroxide combined with UVA for 240 min. An annular reactor containing a UVA lamp (80 W) was employed. A central composite rotacional design was developed employing a TiO/BiPO concentration of 87 mg L and a hydrogen peroxide concentration of 1800 mg L, being evaluated by the degradation percentage and phenol mineralization percentage as responses; 94.
