Abstract
A method, article of manufacture and apparatus are disclosed for binding successive layers of a “guest specie” such as an atom, cation, anion, organic molecule, and/or pathogen to a substrate or multiple different substrates. Possible substrates include materials with a porous nature; macro, micro and nano porous materials are all candidates. The adsorbent capacity of a substrate is extended by coordinating a layer of bi- or multi-functional ligand (L) to an adsorbed atom or ion or molecule or pathogen, which is then coordinate to a second layer of adsorbed atom or ion or molecule or pathogen.
Claims20
An article of manufacture for separating one or more species from a fluid comprising:
- a substrate comprising a porous structure comprising at least one attachment site;
- and
- at least one ligand comprising at least two coordination sites, wherein the at least one ligand binds to the at least one attachment site by one of the at least two coordination sites.
An article of manufacture for separating one or more species from a fluid comprising:
- a substrate;
- at least one specie or surrogate specie adsorbed on the substrate;
- and
- at least one ligand comprising at least two coordination sites wherein one coordination site is bound to the one specie or surrogate specie.
A method for making an article of manufacture for separating one or more species from a fluid comprising the steps:
- a) determining one or more species to be separated;
- b) choosing at least one ligand comprising at least two coordination sites based on the determining of one or more species and the fluid;
- c) choosing one or more substrates comprising at least one attachment site on each one or more substrates;
- and
- d) attaching the at least one ligand to at least one attachment site on the each one or more substrates;
- wherein the at least one ligand binds to the at least one attachment site by one of the at least two coordination sites.
