Effect of silica stabilization on the degradation ability of zerovalent iron nanoparticles.
Original language description
In this study, we focused on the degradation ability of pure and stabilized nanoscale zerovalent iron particles (NZVI) by silica stabilizator for remediation purposes. We studied the degradation of selected chlorinated ethylenes by the aqueous suspensionof iron nanoparticles Nanofer 25. The main problem of iron nanoparticles is their instability in an aqueous solution which leads to aggregation. Previous studies showed that silica compounds provided successful stabilization of nanoparticles. Our nanoparticles were stabilized by a water glass solution. The water glass was simply mixed with the nanoiron suspension. Batch experiments ideally simulated conditions of remediation in contaminated aquifer. The applied concentration of the chlorinated ethylenes (? 0.1mM) and the excess of iron nanoparticles corresponded to the usual values at decontaminated sites. The degradation ability of the pure suspension was verified. At the same time, the effect of the silica stabilizer on the degradati
