FIELD: chemical industry; methods of modification of hydrophilic-hydrophobic properties of the natural organic substances.
SUBSTANCE: the invention is pertaining to the sorbents from the natural substances. The renewable natural organic substances such as the substances of the animals, biological, agricultural origin are heated up in the oxidizing atmosphere at the temperature of 80-700°C, and, depending on the conditions, produce the hydrophobic sorbent or the hydrophilic sorbent. The invention allows to control the hydrophylic -hydrophobic properties of the vegetable organic materials.
EFFECT: the invention ensures control over the hydrophylic -hydrophobic properties of the vegetable organic materials.
