文摘

Inorganic porous materials based on modified sepiolites have been studied as supports for controlled degradation of Lindane, a chlorinated pesticide. In dry media conditions under microwave (MW) irradiation, sepiolite can dehydrohalogenate Lindane to pentachlorocyclohexene (PCCH). Trichlorobenzene (TCB) and PCCH are obtained with NaOH-modified sepiolite and, when nickel oxide is present in the solid, CO₂ is also found as a product of the reaction, in different proportions depending on the surface characteristics.
