ANION-EXCHANGE SORBENT FOR SIMULTANEOUS ION CHROMATOGRAPHIC DETERMINATION OF POLARISABLE AND NON-POLARISABLE INORGANIC ANIONS AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2013 - IPC B01J20/22 B01J20/26 B01J20/30 B01J41/20 B01J41/12

Abstract RU 2496571 C1

FIELD: chemistry.

SUBSTANCE: disclosed is an anion-exchange sorbet based on a styrene and divinyl benzene copolymer with a quaternary ammonium functional group that is chemically grafted to the copolymer through an alkyl or acyl radical (R₁). R₁ is selected from: CH-CH₃, C(O)(CH₂)_n, (CH₂)n, (n= 1-6). The quaternary ammonium functional group contains one methyl radical and two 2-hydroxypropyl radicals. The sorbent has the general formula

R₂ is selected from: H, OH, Hal (halogen), Alkyl (alkyl radical).

EFFECT: invention reduces the effect of the matrix on retention of polarisable anions.

10 cl, 2 tbl, 1 dwg
