Highlights:
- A novel vertical electrokinetics (V-EK) system with multilayer
electrodes was used to mitigate and prevent soil salinization
- The V-EK system in salty soil serves as an “electric sieve” to block
salts
- The salinity of soil can be well mitigated and prevented by the V-EK
system
- The highest Na+ and Cl- inhibition
rates reached >99% and >97%, respectively,
at a voltage of 10-20 V
- The V-EK design could offer a cost-effective and sustainable tool for
preventing upward migration of salt
