Ode, Thanks for all this info. I woke up struggling with the idea of informing people on the methods of saturating AgCl ceramic water purifiers. It's incredibly simple to take a common, ceramic candle filter, saturate with silver nitrate, then run water through it. Then, with the silver chloride disinfectant within the ceramic one ends up with a *highly effective,* and very inexpensive disinfectant against virtually all of the fecal coliform indicators. The *problem* is that you also get something like 1.0 ppm of silver chloride in the water.
Of course, we're still working on silver methods that don't add anything to the water. But in not reporting the AgCl ceramic purifier wouldn't our priorities be askew? Each and every day, somewhere in the world, about 4000 people die of the dehydration caused by dysentery, the result of bacteria contaminated water. It seems a little crazy to deny them so simple an idea as a silver chloride water filter, just because of a remote risk of argyria. Can someone suggest whether or not I should tell people about silver chloride water filters? I'm presently very indecisive. Reid Ode Coyote wrote: Gleaned from various sources.. [don't make me look em up!] Silver chloride is 1/10th as active against micro-organizms as pure silver at a given PPM in vitro. [ie. it still 'works', just not as well] AgCl is photo reactive. It's not very soluable in water and may lead to turning blue if used extensively and other paramters are present. It's not all that toxic but somewhat more so than pure silver. It may form a particle that's too big to stay suspended in water and you might have to shake the bottle up. [If it's that big and not very soluable, seems to me that it'll just pass on through and not do much of anything] It might form in the body from ionic silver anyway [even then different particle sizes forming may have various effects..no clue as to the particulars], or it's formation prevented or partially prevented by metallo protein transport. If you put salt in already made ionic silver water, you'll make some AgCl pretty fast. In small amounts, IMO..no big deal. But why make it on purpose?
