Chlorinated solvents: Market interactions and regulation

Highly Ordered Mesoporous TiO2–Fe2O3 Mixed Oxide Synthesized by Sol–Gel Pathway: An Efficient and Reusable Heterogeneous Catalyst for Dehalogenation Reaction

“…The halogen atoms in these molecules play a very crucial role in directing, substituting, and blocking some positions in the aromatic ring. − These compounds are inexpensive and are used extensively in the industrial process as well as in some daily needs, such as the dry cleaning of clothes, pesticides, etc. , Since these compounds are used on a wide scale, their disposal causes large accumulation of halogenated aromatics in our environment. Furthermore, some of these halogenated organic wastes that are produced in the chemical industry cause various health problems. − The Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) found that these organic wastes of halogenated aromatic compounds have some toxic effect on our ecosystem and health . Thus, an efficient method for the removal of these halogenated compounds is highly demanding, from an environmental perspective.…”

Catalytic Hydrodechlorination of a PCB Dielectric Oil

“…Production of PCBs was banned in U.S.A. in 1979 and in the successive years in the European countries due to their toxicity (1). Large amounts of PCBs have been used mainly as dielectric fluids in transformers and capacitors, and a fraction of them is still in use or has been disposed in landfills (2).…”
