The market is covered by several commercial available materials of nanoiron particles. Because of its individual production and modification, each material is the specific reduction agent which degrades contaminants with a different efficiency. This study deals with the ability of the zerovalent iron nanoparticles in the form of a suspension to degrade chlorinated ethylenes. Using batch test we tested two the suspensions RNIP 10APS and NANOFER 25. For assessing of the degradation ability, kinetic parameters were evaluated. In the case of the experiments with RNIP 10APS, the chlorinated ethylenes were degraded by first order kinetics. The tendency of the degradation rates was trichloretylene}tetrachloretylene}dichlorethylene. The degradation of the chlorinated ethylenes by NANOFER 25 shows also first order kinetics. The tendency of the degradation rate has a distinct character than we observed in RNIP 10APS."@en . "Janou\u0161kovcov\u00E1, Petra" . . "22320" . "Vodn\u00ED zdroje Ekomonitor spol.s r.o." .
