I copied the following from a web site. There has been a lot about
chelated silver in our magazines and wanted to know how to make it if
it can be made at home? Has
anyone had any experience making Chelated Silver? Does it have draw
backs that our cs doesn't?

*Chelated Silver*™ is silver ions *in solution*. It is vastly
different from the silver-based dietary supplement products known as
*colloidal silver* <http://nccam.nih.gov/health/silver/#>, which is
silver *in suspension*. In colloidal silver, finely divided particles
of elemental silver are randomly floating in suspension in water and
are not evenly dispersed. In CHELATED SILVER™, ions of pure,
crystallized silver nitrate are chemically bonded to nonmetallic ions,
and are therefore evenly dispersed throughout the solution. _This
bonding in solution considerably enhances Chelated Silver™'s
antimicrobal action and persistance_ (killing power over time).
In colloidal suspensions, minute silver particles of elemental silver
are suspended or randomly floating in water, typically at a level of
*10-50 parts per million*. Chelation occurs when a metal ion forms a
heterocyclic bond with a bidentate ligand. Examples of bidentate
ligands are carbonate and oxalate ions and ethylenediamine. As a
general rule, five- or six-member lingands are favored. Chelated
Silver™ ions are chemically bonded to nonmetallic ions and are evenly
dispersed throughout the solution. This concentrated and uniform
dispersal of Chelated Silver™ ions (typically at a level of *300 to
400 parts per million*) throughout the solution considerably enhances
their antimicrobial action, persistence and effectiveness.
*Chelated Silver*™ is highly effective in blocking the respiration of
microorganisms causing them to expire. Additionally, scientific
testing is in progress to study the effectiveness of Chelated Silver™
in interdicting anaerobic bacteria (bacteria that exists in the
absence of oxygen).
They seem to be contradicting themselves here. They say that colloidal
silver is less effective than their chelated silver, yet they indicate
that their chelated needs to 10 to 50 times as strong as colloidal to be
effective. Sounds like doublespeak to me.
