Hepure: Iron Disulfide Supplier/Iron Pyrites Distributor
Iron Pyrite/iron disulfide, distributed by Hepure, is a pure, finely grained, mono-crystalline of iron pyrites (FeS 2). Like zero valent iron (ZVI), iron disulfide can degrade numerous chlorinated hydrocarbons completely into non-contaminated hydrocarbon or sulfur compounds via a reductive elimination process.
