Scientists developed a method that allows removal of antibiotic residue from waste water

A new article is focused in particular on organic aerogels produced from phenolic compounds obtained upon processing Estonian oil shale, i.e. from local raw material. In order to produce highly porous aerogel from gel, supercritical extraction with carbon dioxide is used, in the process of which liquid is replaced by gas resulting in aerogel -- a very light and porous material.
