DDT, DDD, and DDE chlorination by zero-valent iron
Article Abstract:
Zero-valent iron was found capable of dechlorinating chlorinated aliphatics and aromatics such as DDD, DDE, and DDT. The powdered zero-valent iron in buffered anaerobic aqueous solution was able to dechlorinate the pesticides at rates independent of the amount of iron and the presence of surfactants. A mechanistic model had demonstrated that the rate of dechlorination of the solid-phase reactants is influenced by the rate of dissolution into the aqueous phase.

Reductive dechlorination of 1,2,3,4-tetrachlorodibenzo-p-dioxin and its products by anaerobic mixed cultures from Saale River sediment
Article Abstract:
Anaerobic bacteria from sediment of the river Saale in Germany appears to dechlorinate 1,2,3,4-tetrachlorodibenzo-p-dioxin (1,2,3,4-TCDD). The main product of the dechlorination process is 1.3-dichlorodibenzo-p-dioxin, which is the result of the loss of a lateral chlorine atom from the intermediate compound, 1,2,4-trichlorodibenzo-p-dioxin. The dechlorination of 1,2,3,4-TCDD was also studied using other soils and sewage sludge.

Natural sorbents in oil spill cleanup
Article Abstract:
In a laboratory setting, milkweed and cotton fibers sorbed more crude oil from sea water than polypropylene fibers or webbing did. The milkweed fiber sorbed 40g of crude oil/g of fiber. The oil sorbed by the natural fibers can be recovered and the fibers used several times. The natural fibers are also biodegradable.
