Remediation of soils and sediments polluted with polycyclic aromatic hydrocarbons: To immobilize, mobilize, or degrade?

Manish Kumar et al.

Summary: PAHs are generated due to incomplete burning of organic substances, primarily influenced by the use of fossil fuels. They impose health impacts on humans and other living organisms due to their carcinogenic, mutagenic, or teratogenic properties. Their high hydrophobicity and low water solubility influence their adsorption onto soils and sediments, affecting their bioavailability and subsequent degradation.

Removal of volatile organic compounds from the coal-fired flue gas by adsorption on activated carbon

Xiuwei Ma et al.

Summary: The removal of VOCs from coal-fired power plants is crucial in reducing emissions into the atmosphere. Adsorption on activated carbon is an effective method but can be affected by factors such as temperature and the presence of other gases. Competitive adsorption may occur when SO2, water vapor, and fly ash coexist, impacting the overall VOCs removal efficiency. Selecting activated carbon with large micropore volume and extending adsorption time can enhance the VOCs removal process.
