Abstract: This paper is focused on the possibility of using iron nanoparticles (nZVI - nano zero-valent iron) to remove selected specific synthetic substances, such as hexachlorobutadiene, pentachlorobenzene, hexachlorobenzene, lindane and heptachlor. Experimental measurements were performed in order to evaluate the effectiveness of the removal of substances and their specific removal rate. Evaluation of the results shows that nanoiron NANOFER 25 is a convenient reactant for the removal of heptachlor, lindane and hexachlorobenzene; while for pentachlorbenzene and hexachlorobutadiene removal, longer contact times are necessary to achieve significant removal efficiencies.
Keywords: nanoiron particles, nZVI, organochlorinated substances, persistent substances, priority substances, zero - valent iron
