Impregnated activated carbon removes gaseous pollutants like Hydrogen sulfide can be effectively captured by impregnated activated carbon and converted to sulfur.

Hydrogen sulfide generated/emitted by petrochemical plants, food plant, processing plants, semiconductor plants, sewage treatment plants, or pharmaceutical plants. Generally, the effluent gases from such plants are treated by washing followed by neutralization with chemicals, adsorption onto activated carbon, condensation, masking, or direct or catalytic combustion. RXSOL  impregnated activated carbons have been developed with superior deodorizing performance.
