Effect of Physico-chemical Activation on Sorption Activity of Bio-coal from Pine Sawdust

Pine sawdust, 0.5–1 mm in size, was made carbonized. The resulting biochar was activated. This activated KOH biochar was confirmed to be a better methylene blue dye sorbent than the original charcoal. The conclusion was made about the possibility of using the study results in the processing of timber industry waste into carbon sorbents for water treatment systems and ensuring environmental safety of production sites.
