The addition of FA to ball-milling could dramatically enhance the performance of ball-milled ZVI (ZVI bm) towards Cu(II)-EDTA removal and increase the removal rate constant by 80 times. This conspicuous improvement of Cu(II)-EDTA elimination was attributed to the ferrous formate (Fe(HCOO) 2 ) shell formed on the surface of FA-ZVI bm .

Mechanochemical sulfidation is a facile and promising approach for sulfidating microscale zero-valent iron (mZVI). Compared to simple ball-milling of mZVI that reduces particle size and exposes reactive Fe 0 surface, ball-milling of mZVI with S 0 results in sulfidation and at the same time greater size reduction [15].The rate and electron efficiency of TCE …
