The DDT is soluble in DMSO, so it is already possible to separate from soil.
The problem has been that the DDT isn't really useful, so you're still left over with DDT tainted DMSO. Hence, most cleanup efforts focus on sequestration of soil.
The electrolysis step creates benzene and other hydrocarbons, making a useful byproduct. This means there's a better incentive to treat it rather than store it.
- sargun 10mo agoSo, you’re essentially washing the soil in DMSO, and DDT is more soluble in DMSO? — curious, what does it take to wash all that soil?
- zdragnar 10mo agoAssuming it doesn't break down under electrolysis, the DMSO can be recovered, so you only use as much as you can process at a time. It is apparently used in some battery chemistries, so I'd expect losses to be pretty low if the equipment is set up well.
