MT-V3 safely and readily decomposes Volatile Organic Compounds (VOCs) of contaminated soil and water in pH neutral conditions, thereby reducing environmental contamination.

Chief components

  • Iron oxide
  • Iron powder

Intended use

  • Decomposition of VOCs (Trichloroethylene etc.)
  • POPs including dioxin and residual agricultural chemicals can also be decomposed.

Decomposition test of Trichloroethylene

  • Trichloroethylene (TCE)
  • Initial concentration 10.0mg/L
  • MT-V3 additive amount 25g/L - polluted water

The amount of chloride ions as decomposed material almost equals the theoretical amount, so no harmful by-products are generated through the decomposition process.

Free from rusty water

The iron ions leached from iron powder are immobilized by MT-V3 on the surface of iron oxide particles, and it is free of concern about the generation of rusty water.
