Ball-milling synthesis of biochar and biochar–based nanocomposites and
Ball milling coupled with elevated pyrolysis temperature resulted in the synthesis of micro–nano–engineered sized and high surface area biochar composites. Ball milled nano–biochar (NBC) with the surface area of 28 m 2 /g showed higher sorption capacities of 922, 7.46, 520 and 83 mg/g, for the removal of (Cd(II)), ...
Modification of biochar with high-energy ball milling: Development of
The biochar samples were ball milled in a high-energy planetary ball mill (Pulverisette 6, Fritsch, Germany) using ZrO 2 grinding bowls (80 mL); 2 g of biochar was placed in the bowl with 100 g of ZrO 2 balls (⌀ 5 mm, ball:sample mass ratio of 50:1, as recommended by the manufacturer). One sample (Pulp Sludge) was ball milled with 25 …
