Morphological and mineral features of nZVI-induced precipitation on quartz particles

This study investigated the morphological and mineral features of nano zero-valent (nZVI)-induced iron precipitation on quartz particles. Lead was employed as artificial contaminant, while used to mimic inert solid particles in soil. The characterisation indicate that minerals precipitated heterogeneously surface with plush-like flake-like structures. They are made deuterogenic plumbiferous ferriferous minerals, amorphous structure. curly clusters had a scattered distribution along corroded nZVI aggregation. thickness varied from 20 60 nm, 35 nm. generation these precipitations led slight increase average particle size decrease area However, no clear difference shape roughness found after treatment. performed improve understanding mass transfer soil its effect improvement.
