ABSTRACT:
Iron and ferrous sulfide in specific amounts are combined under aerobic or anaerobic conditions to reduce halogenated hydrocarbons in aqueous compositions to non-toxic by-products at near neutral pH and Eh values below -325 mV. The combination of iron metal and ferrous sulfide in relative amounts gives the unexpected result of a faster reduction rate using iron or ferrous sulfide alone and a controlled pH.
