Abstract
Caffeine-adsorbing materials, caffeine-adsorbing systems, and decaffeination system suitable for removing caffeine from a solution; methods for removing caffeine from a solution; and methods of making the caffeine-adsorbing materials are described.
Claims17
A method of removing caffeine from a solution comprising:
- contacting the solution with a caffeine-adsorbing material comprising:
- a crosslinked polymer, wherein the crosslinked polymer comprises alginate and a crosslink, wherein the crosslink is a multivalent ion, and wherein the crosslinked polymer is a crosslinked hydrogel;
- and
- a caffeine adsorbent associated with the crosslinked polymer,
- for a time and under conditions sufficient to adsorb caffeine, thereby removing caffeine from the solution,
- wherein the caffeine-adsorbing material is thermostable at temperatures equal to or less than 150° C.

A caffeine-adsorbing material comprising:
- a crosslinked polymer, wherein the crosslinked polymer comprises alginate and a crosslink, wherein the crosslink is a multivalent ion, and wherein the crosslinked polymer is a crosslinked hydrogel;
- and
- a caffeine adsorbent associated with the crosslinked polymer,
- wherein the caffeine-adsorbing material is thermostable at temperatures equal to or less than 150° C.
1 more element
A caffeine-adsorbing system comprising:
- a porous container;
- and
- a caffeine-adsorbing material disposed within the porous container, the caffeine-adsorbing material comprising:
- a crosslinked polymer, wherein the crosslinked polymer comprises alginate and a crosslink, wherein the crosslink is a multivalent ion, and wherein the crosslinked polymer is a crosslinked hydrogel;
- and
- a caffeine adsorbent associated with the crosslinked polymer,
- wherein the caffeine-adsorbing material is thermostable at temperatures equal to or less than 150° C.
4 more elements
A decaffeination system comprising:
- a caffeine-containing solid;
- and
- a caffeine-adsorbing material comprising:
- a crosslinked polymer, wherein the crosslinked polymer comprises alginate and a crosslink, wherein the crosslink is a multivalent ion, and wherein the crosslinked polymer is a crosslinked hydrogel;
- and
- a caffeine adsorbent associated with the crosslinked polymer,
- wherein the caffeine-adsorbing material is thermostable at temperatures equal to or less than 150° C.
