CPII-Z™ is a zeolite-based, potassium permanganate-impregnated media for oxidation of inorganic and organic contaminants. The spent (used) potassium permanganate media cannot be recycled or incinerated to end the generator’s waste liability, as is possible with activated carbon, and must be disposed in a landfill. In addition, the capacity of permanganate impregnated-media, defined as total inorganic or organic material removed per pound or volume of media, is less than that of activated carbon. Potassium permanganate-impregnated media is primarily recommended for applications where activated carbon is not an effective adsorbent such as for the oxidative removal of carbon monoxide, methane, ethane, ethylene, propane, and propylene.
Activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low oxygen spaces should be followed, including all applicable Federal and State requirements.
