THE SELECTIVE REMOVAL OF CHEMICAL SPECIES FROM A FLUID

摘要

An element for use in the selective removal of a chemical species from a fluid comprises an impervious support sheet having adhered thereto a layer of a polymer having at its surface functional groups which are directly or indirectly reactive with a ligand for the species. The element e.g. in the form of a coil can be housed in an apparatus through which the fluid can be passed. A method of removing a chemical species from a fluid comprises passing the fluid over the surface of the element having a ligand for the species covalently attached thereto. A specific example of the use of the invention is the separation of a protein from a mixture of proteins.
