HOME > Products > Environmental Products > MT-V3 Iron oxide-based VOCs decomposer

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.

MT-V3 does not generate rusty water.

Decomposition performance of VOCs

Decomposition performance of VOCs	Decomposition rate constant(hr^-1)
Carbon tetrachloride	1.1×10^-1
1,1-Dichloroethane	1.7×10^-2
cis-1,2-Dichloroethane	2.7×10^-2
Tetrachloroethylene	1.5×10^-2
1,1,1-Trichloroethane	7.6×10^-2
1,1,2-Trichloroethane	3.5×10^-2
Trichloroethylene	2.3×10^-2
