A Fritsch planetary ball milling machine, Pulverisette 7 Premium line has been utilized to mix the powders. WC-Co vials and balls were employed to avoid contamination. For each milling, the ball-to-powder ratio was kept constant at 4:1 and the milling time was set at 6 h (three separated steps of 2 h effective milling each) .

Milling experiments were also conducted on soils from a Canadian firefighting training area (FFTA), demonstrating that PFOS concentrations can be reduced by up to 96% in site soils. For the first time, ball milling for the remediation of PFAS in environmental media has been demonstrated using amended sand and legacy soils from a FFTA.

Ball milling is effective in shortening the reaction time as the grain refinement of the GIS phase, as shown in Figure 5a–d. The highest HGR (HGR) occurs in advance and with a higher value versus the crushing powder. The HGR reaches over 4000 mL·min −1 for both ball milling alloy powders with NiCl 2 as shown in Figure 6a,c and Table 3.

In the present work, the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during collisions among milling media.

For the LTER deep core soil samples, a sieved soil sample from each treatment, sampling station, and soil depth is oven dried at 60 degrees C for at least 48 hours until no further mass loss occurs. Air dried soil can also be used. The sample is then pulverized to a fine powder using a swing mill pulverizer (similar to a ball mill) and placed into polyethylene vials for storage.

Despite many reports on ball milling (BM) of chitin, the effect of cryomilling of chitin has not yet been reported, even though it is a solventless and environmentally-friendly method for the processing of chitin polymer. In this work, commercially available chitin has been cryoground for up to 96 min and th Marine-based Green Chemistry
