METHOD OF INCREASING ABSORPTION OF AMMONIUM IONS WITH VERMICULITE, ABSORBENT MATERIAL, USE THEREOF AND METHOD OF REMOVING AMMONIA FROM ENVIRONMENT

摘要

FIELD: chemistry. ^ SUBSTANCE: present invention relates to vermiculite based adsorbents. Untreated vermiculite is heated at temperature at which the third vermiculite decomposition step takes place. Heating is carried out to temperature at which interplane distance of vermiculite Cd002 is equal to 9.9-12 A. The invention discloses use of the obtained vermiculite as an absorbent material, as well as soil fertiliser/conditioner. ^ EFFECT: invention increases ammonia sorption capacity of vermiculite. ^ 12 cl, 2 dwg, 6 tbl, 3 ex
