TY - JOUR A1 - Noubactep, Chicgoua T1 - On the suitability of admixing sand to metallic iron for water treatment Y1 - 2013 VL - 1 IS - 1 SP - 22 EP - 36 JF - International Journal of Environmental Pollution and Solutions DO - 10.7726/ijeps.2013.1004 DO - 10.23689/fidgeo-2512 N2 - This communication clarifies the relationships between sand addition and the sustainability of iron/water systems for environmental remediation. It is shown that any enhanced contaminant removal in an iron/sand/water relative to an iron/water system is related to the avoidance/delay of particle cementation by virtue of the inert nature of sand. The argument that sand dissolution produces protons (H+) to sustain iron corrosion is disproved by the very low dissolution kinetics solubility of SiO2-bearing minerals under environmental conditions. This demonstration corroborates the concept that aqueous contaminant removal in iron/water systems is not a process mediated by electrons from Fe0.
