Herein, NiCr2O4 nanostructures were successfully prepared via a facile and solvent-less ball milling method using new set of organometallic starting reagents including Ni(Sal)2 as nickel source and [Cr(en)3]Cl3.3H2O as chrome source. Effect of ball mill time, speed of ball mill, mass ratio of ball to powder and process control agent on morphology of as-prepared NiCr2O4 …
The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm.
