Effect of microscopic additions of fullerenes on the absorption capacity of inorganic sorbents for d elements

Abstract

It was shown that raising the sorption activity of an industrial silica gel of KSK-G brand and zeolite of NaX brand via their surface modification with microscopic amounts of fullerenes (1.0 × 10–3, 2.0 × 10–3, and 5.0 × 10–3 wt%) is possible and promising. The low content of fullerenes in the modified samples predetermines the economic basis of their practical applications. The sorption activity of the modified sorbents (up to 30%) exceeds the similar characteristic of the starting industrial sorbents.
