FIELD: technological processes. ^ SUBSTANCE: invention is related to the field of environment protection, namely to sorbents for treatment of sewage water, gas exhausts and oil spills, and for ion-exchange treatment of plating industry drains. Method for production of sorbent includes grinding of initial components, mixing, carbonisation, activation, flushing with return alkaline solutions and drying, at that initial components are used: peat, aluminium silicate and black coal, which are ground down to the following particle size, mm: peat 1.0-3.0, aluminium silicate 0.1-0.3, black coal 0.1-0.3, carboniaation is carried out at temperature of 750-800C for 15 minutes without air access, and activation is done in boiling layer in flow of mixture of carbonic acid gas and water vapor at temperature of 750-800C for 15-30 minutes or in atmosphere of oxygen for 3-5 minutes. ^ EFFECT: production of material with developed specific surface and ion-exchange properties, and also reduction of negative effect at environment in process of production. ^ 1 tbl |
