ZVI (Fe0) desalination: catalytic partial desalination of saline aquifers

Globally, salinization affects between 100 and 1000 billion m3 a−1 of irrigation water. The discovery that zero valent iron (ZVI, Fe0) could be used to desalinate water (using intra-particle catalysis in a diffusion environment) raises the possibility that large-scale in situ desalination of aquifers could be undertaken to support agriculture. ZVI desalination removes NaCl by an...
