Some physicochemical properties of carbon adsorbents produced by chemical activation with
alkali are determined: specifically, their total ash content, the content of water-soluble ash, the total iron content
(recalculated for Fe3+), and the content of water-soluble iron compounds. Their content of water-soluble
ash and the total iron content are minimal; no water-soluble iron compounds are observed in the sorbents.
However, the total ash content in the sorbents is impermissibly high. With increase in potassium content in
the initial content, the total ash content of the sorbents is reduced to 16.5%.
