摘要：

Activated carbons of grades AG-5, SKT-6A, and LiderKarbon-E, impregnated with copper sulfate with an additive content of 10-20 wt % and modified with fullerenes in the amount of 0.003-0.006 wt % were prepared and studied. The introduction of additives reduces the volume of micropores up to 36% with a slight decrease in the volume of mesopores. Modification of activated carbon by fullerenes increases its dynamic benzene capacity in humid environments by 28-36%, and the introduction of fullerenes into a chemical adsorbent based on activated carbon modified with copper sulfate increases its dynamic ammonia capacity by 45-51%, especially at high air humidity.
