Photo-Fenton-like degradation of bisphenol A by persulfate and solar irradiation.

This work evaluates the feasibility of a solar-enhanced Fenton-like process using SO (PS) and Fe for the elimination of BPA, a model endocrine-disruption compound. This comparative study of BPA removal showed that among the approaches employed, the effectiveness of BPA degradation (10 mg/L) decreased in the order: Solar/PS/Fe> Solar/PS > PS/Fe> Solar/Fe> Solar. The complete degradation of BPA was achieved by Solar/PS/Fe treatment at a [PS]:[BPA] ratio of 20 in less than t 5 in deionised water.

Oxidation of atrazine in aqueous media by solar- enhanced Fenton-like process involving persulfate and ferrous ion.

The oxidation of s-triazines (using atrazine (ATZ) as a model compound) by a solar-enhanced Fenton-like process involving persulfate and ferrous ion was studied. A flow-through tubular photoreactor was employed for the experiments. The solar-enhanced oxidative system involving ferrous ion and persulfate (Solar/SO/Fe) showed the highest ATZ degradation efficiency when compared with other treatments (unactivated SO, Solar - sunlight only, SO/Fe, Solar/SO).
