Abstract RU 2502679 C1

FIELD: chemistry.

SUBSTANCE: invention can be applied for purification of technological sewages of chemical industry enterprises. Method of purifying water solutions from pyridine by adsorption by activated coal includes processing of activated coal with ammonium chloride with concentration 5 mg/dm³ for 3 hours. Ratio of activated coal weight to volume of ammonium chloride constitutes 1:100. Pyridine adsorption from its water solution is carried out in static conditions.

EFFECT: invention makes it possible to increase efficiency and economy of purification process.
