Abstract. There is a need for destructive technologies for per and polyfluoroalkyl substances (PFAS) in soil. While planetary ball mill have been shown successful degradation of PFAS, there are issues surrounding scale up (maximum size is typically L cylinders). While having lower energy outputs, horizontal ball mills, for which scale up ...

All ball milling trials were run in triplicate (with one extra FFTA clay at the 25 L scale), with duplicate samples being collected at each time interval. Samples were collected prior to the start of milling (T0), every 10 min across the first hour ( T10, T20, T30, T40, T50 and T60), and then at the 2h (T120) and 3h (T180) marks.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
