Abstract:
1. A method of removing a selected metal-ion from a liquid, comprising the steps of: providing a container for holding said liquid, said container comprising an internal surface having a metal-ion sequestering agent immobilized in at least a portion of said internal surface for removing a designated metal-ion from said liquid, wherein said metal-ion sequestering agent comprises derivatized nanoparticles comprising inorganic nanoparticles having an attached metal-ion sequestrant, wherein said inorganic nanoparticles have an average particle size of less than 200 nm and the derivatized nanoparticles have a stability constant greater than 10 filling said container with said liquid in an open environment; closing said container with said liquid contained therein; said metal-ion sequestering agent removing said designated metal-ion from said liquid; and shipping said container for use of said liquid without any further processing of said container containing said liquid.
