METHOD OF SELECTIVE BINDING SUBSTRATE TO SORBENTS THROUGH AT LEAST BIVALENT BONDS Russian patent published in 2008 - IPC B01J20/32 B01J20/281 G01N33/50 

FIELD: chemistry.

SUBSTANCE: sorbent, with at least two different groups, which are capable of selective bonding with a substrate, consists of stages (i)-(ii): (i) definition of at least two groups, capable of bonding with a sorbent made from synthetic or natural first substrate, (ii) respectively, depositing of at least two different groups, capable of bonding the second synthetic or natural substrate, to one corresponding carrier, thereby forming at least one sorbent. The groups are the same as those groups on stage (i) or are groups, which are complementary them, and the second substrate on stage (ii) is the same as the first substrate corresponding to stage (i) or different from it. The groups are such that the component of Gibbs energy of individual groups in noncovalent bonds with the second substrate yield a negative value of Gibbs energy ΔG, so that there is stronger bonding, which leads to improvement of selectivity of separation relative to at least one substance, which should separate.

EFFECT: obtaining a sorbent capable of selecting a substrate.
