Disclosed are a modified nanoscale zero-valent iron (nZVI) and a preparation method and an application thereof. The preparation method of the modified nZVI includes the following steps: S1: mixing nZVI, a stabilizer and an oxidant together and stirring in an inert atmosphere to obtain a polymerization precursor solution; and S2: dripping pyrrole into the polymerization precursor solution prepared in the S1, maintaining an inert gas atmosphere for polymerization reaction, and performing cooling, filtration and vacuum drying to obtain the modified nZVI. According to the preparation method of the modified nZVI in the present disclosure, nZVI, stabilizer and oxidant are mixed to prepare a polymerization precursor solution, into which pyrrole is added for polymerization to obtain uniformly-coated modified nZVI, thereby forming a comprehensive mechanical support, which cannot only effectively improve oxidation property and structural stability of nZVI, but also promote reactivity of nZVI with heavy metal (semimetal) ions or radioactive elements.

A method of manufacturing granules is provided. The method includes flowing an inert gas and a fluorine-containing gas into a plasma source at a first ratio; generating a fluorine-containing plasma from the inert gas and the fluorine-containing gas by the plasma source; and applying the fluorine containing plasma to porous carbon granules in process chamber.
