Previous studies confirmed a positive stabilization effect of silicate on iron nanoparticles. The ability of pure iron nanoparticles NANOFER 25 to degrade chlorinated ethylenes was verified by a batch experiment. The degradation experiment with the modified iron nanoparticles were performed in parallel. The iron nanoparticles were characterised by BET. During the experiments, we measured a content of zerovalent iron available to degradation simultaneously with content of contaminant in a degradation suspension. The results indicated that the fastest degraded chlorinated ethylene by pure nanoparticles was dichlorethylene (kobs = 0,126 d-1). Experimental data showed that the surface modification supports the degradation of the chlorinated ethylene at the beginning of the experiment. However, the degradation of higher chlorinated ethylene (TCE) was uncompleted. The accelerated degradation of the modified particles was accompanied by a rapid consumption of the zerovalent iron."@en . .
