FIELD: chemistry.
SUBSTANCE: proposed nano-sorption medium has a matrix with a meso-, macroporous structure - gamma aluminium oxide, made from primary blocks with 3-9 nanometre dimensions, and modifying components: 3.0-10.0 wt % hill-growing saltwort extract in the end product and up to 4 wt % lithium citrate in the end product. The packed density of the sorbent is 0.76-1.1 g/cm3 depending on grain-size composition and content of the modifier on the surface of the sorbent.
EFFECT: when the obtained sorption medium is in contact with liquid media, it prolongs extraction of modifiers from the surface.
