Oxidative Liquid-Phase Detoxification of Organochlorous Components of Wastewater

The possibilities of creating high-activity low-percentage ruthenium catalysts based on the (Ru+CeO₂ +ZrO₂)/C system for the neutralization of highly toxic organochlorine components of wastewater by the method of liquid-phase oxidation with atmospheric oxygen are considered. Shown that the use of Ru-CeO₂-ZrO₂ – carbon catalysts with a low content of Ru (up to 0.6 % wt.) and with a high dispersion of particles of both the active component and the promoter, makes it possible to achieve high degrees (up to 95 %) of water purification from dissolved organochlorine substances at relatively low temperatures (160–180 °C). The ability of catalysts to synthesize the active component in the studied reaction mixtures during testing.
