Carbon monoxide (CO) is a very toxic gas with TLV of 35 ppm and it is to be removed from the air in mines, enclosed spaces, fire breaking places. Active carbon can not hold the CO due to physisorption and therefore palladium impregnated carbon was developed which became even more active due to high RH. This again one of the very specialized carbon exported by us for air purification and CO removal. It almost works like the turn over catalyst and offers very high protection against CO. This carbon has High Surface area providing almost offers endless protection against CO, Works in any RH but becomes more active at high RH.
