FIELD: woodworking industry. ^ SUBSTANCE: invention is related to sorption engineering and may be used for production of adsorbent in the form of charcoal applied for lead ions adsorption from water medium. Adsorbent preparation includes pyrolysis of natural wood of soft hardwood - aspen, which is at first compacted, then exposed to thermal treatment and, afterwards, pyrolysis. Produced charcoal is crushed and separated, at that wood is compacted prior to pyrolysis 2.5 times relative to initial volume. In process of separation fraction charcoal is taken out, for instance 0.1-0.3 mm. ^ EFFECT: invention provides for expansion of technological possibility for water medium purification from lead ions due to application of suggested adsorbent at minimum duration of water medium purification process and increased quality of purification. ^ 1 tbl |
