mplacement of meso zero-valent iron particles (mZVI) in
porous media to degrade organic pollutants (Phenol as
model pollutant) in continuous column studies is first of its kind.
Columns with different configurations varying in ZVI distribution
and location of H

were investigated for factors influencing
sustainable phenol removal. The performance of columns were
in the ascending order of C > A > B > D where columns A and
B had full-length ZVI distribution, C and D had half-length ZVI
distribution, with H

injection at initial conditions in A and
C and at intermittent points in B and D. Distribution of mZVI
particles in column C contributed 61-84% more interaction

retained active iron surface area and circumvented precipitation
and secondary sludge production. The breakthrough curves
showed that mZVI particles extended the active corrosion stage
by 5 to 8 times and resulted in 3 to 7 times increment in mg
phenol removed/mg mZVI along with 80% to 99.8% utilization
of mZVI. Additional sand-only columns proved that Fenton’s
oxidation in in situ porous media can be improvised by 14% to
34% without incumbent addition of ZVI particles.
