FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing an adsorbent based on activated carbon. The method includes a novolac resin synthesis step, a composite phenolic resin production step, wherein in a solution obtained by the novolac resin synthesis step, formaldehyde and a basic catalyst are heated with stirring to synthesize a resole resin component and produce a composite phenolic resin containing novolac resin content. Then, a carbonization step is carried out, where the composite phenolic resin is carbonized to obtain a resin carbide, and an activation step, where the resin carbide is activated to obtain an activated carbon adsorbent.
EFFECT: increasing the adsorption characteristics of the adsorbent.
