BLAS LOPEZ, H. A et al. Optimal conditions for oxidizing phenol in water by fenton and Photo-Fenton processes. Rev. Soc. Quím. Perú [online]. 2017, vol.83, n.4, pp.437-441. ISSN 1810-634X.

Phenol can be degraded to almost 100 % within a few minutes via Fenton and photo-Fenton processes. Its degradation and the ratio of initial molar concentrations of oxidant and catalyst increase in inverse senses, and a ratio of 38.4 was optimal for aqueous solutions contaminated with 20 ppm of phenol. In addition to this, the use of ultraviolet-A light enhanced degradation when compared to shorter wavelengths.
