Resumen

This paper presents the results of a study of the photocatalytic activity of iron-containing composites based on natural peat and zeolite under external influences: Ultraviolet irradiation (UVI) and UVI + H2O2. It is shown that the optimal method for the photocatalytic destruction of pollutants (oxalic acid and phenol) with composites is to introduce hydrogen peroxide in the system. The composites studied are sources of iron ions in the Ruff-Fenton system; they provide the generation of ?OH radicals, which have a high reactivity in the oxidative degradation reactions of organic substances and can be recommended for reuse to purify water drains.
