I am working with eutectic solvents to extract bioactive compounds and want to recover them, however, when trying to use the anti-solvent technique (water, 1:20), the solvent components do not separate.
The indexes NDWI and MNDWI are use to identify waterbody. Can I use these index to identify wetland also? Thank you for advance.
