Comparison of Migration and Reactive Properties of New Types of Iron Nanoparticles

Popis výsledku v původním jazyce

The submitted work presents the results of comparative laboratory tests focussing on a comparison of the reactive and migration properties of new types of iron nanoparticles (nZVI). Specifically, the results of batch tests and column tests of a new type of non-pyrophoric iron powder STAR with additional surface modification using various organic stabilizers were compared a standard, commercially available nanoiron product called NANOFER 25S (N25S) from the manufacturer NANO IRON s.r.o. The test results show the different character of the powders in terms of reactivity and migration, which is given by the different method of preparation, whereby the surface of the resulting particles is coated by an oxide layer and has a higher mean size. In general, it can be stated that the STAR powder is slower to react than N25S due to the gradual breakdown of the surface shell of the oxides and has slower migration properties due to the lack of smaller fractions with high mobility
