A method for anion-exchange adsorption and anion-exchangers |
| abstract |
A method for the removal of a substance carrying a negative charge and being present in an aqueous liquid (I). The method comprises the steps of: (i) contacting the liquid with a matrix carrying a plurality of ligands comprising a positively charged structure and a hydrophobic structure, and (ii) desorbing the substance. The characterizing feature is that (I) each of said ligands together with a spacer has the formula: -- SP---[Ar-R1-N+(R2R3R4)] where (A) [Ar-R1-N+(R2R3R4)] represents a ligand a) Ar is an aromatic ring, b) R1 is [(L)nR'1]m where n and m are integers selected amongst zero or 1; L is amino nitrogen, ether oxygen or thioether sulphur; R'1 is a linker selected among 1) hydrocarbon groups; 2) -C(=NH)-; c) R2-4 are selected among hydrogen and alkyls; (B) SP is a spacer providing a carbon or a heteroatom directly attached to Ar-R1-N+(R2R3R4); (C) --- represents that SP replaces a hydrogen in (Ar-R1-N+(R2R3R4); (D) -- represents binding to the matrix; and (II) desorption. There is also described (a) anion-exchangers having high breakthrough capacities, (b) a screening method and (c) a desalting protocol. |
