da ponovim da sam slab sa engleskim, ali znam dovoljno da vidim da neki clanak valja.
ima li dobra dusa da prevede makar bitne delove ovog dole
sustina je
sto sitnije to delotvornije
i moje glavno pitanje je:
da li neko zna
da li je bolje koristiti manju struju tj. gustinu struje i da li to ima efekta na velicinu cestica i samim tim na njihovu delotvornost
ako koristimo gustinu struje od 0.05mA/cm^2 da li dobijamo duplo manje cestice nego ako koristimo 0.1mA/cm^2
ili su cestice priblizne velicine?
zna li neko?
hvala

What is Colloidal Silver?
Colloidal Silver is basically silver particles suspended in water. These sub-microscopic particles are neither filtered nor deposited at the bottom of the container. Other than silver particles, silver ions (a silver atom with one electron removed and has a positive charge) too can be present in colloidal silver products.
PPM (parts per million) refers to the concentration of the material in a medium. The same number is derived if you find milligrams of silver per liter (mg/l) of water. Thus mg/l and ppm are the same. Different companies sell colloidal silver of different concentration. The concentration of 20ppm has the qualities of fine size particles, uniform suspension and silver particles in ionic state are lesser than 20% of the total silver content.
The size and concentration of silver particles are variable (1 nm to 1000 nm). The variations are due to different factors including the purity of the silver, purity of the water and the speed of manufacturing process. The smaller the particle size, the better its performance will be.
The Manufacturing Process
The manufacturing of colloidal silver is akin to electrolysis process, where silver wires act as the electrodes and distilled water with a little of colloidal silver as the electrolyte. The electrodes used are pure .9999 (99.99%) silver rods and the water is distilled. Tap water, water purified by reverse osmosis etc are not used in the production of colloidal silver. No salt is added to increase the conductivity of the water either.

Basic Colloid Facts
We must first state that most texts refer to a colloid as
"suspended particles in the 1 to 1,000nm (0.001 to 1 micron) size"
but practical colloids include sizes up to 10,000 to 100,000nm (400 millionths to 4 thousands of an inch) - many paints being good examples! Natural milk is a unstable colloid, with the large fat globules rising to the top in a day, while pasteurized milk (with smaller fat globules) is much more stable, until it sours, rapidly forming large particles.
A colloid is not in fact a suspension, as the definitions state:
a suspension is particles larger then 1 micron (1,000 nanometers)
colloidal particles are defined as 1 nm to 1,000 nm
a solution (ions) is defined as particles less then 1 nm in diameter.

What is popularly refered to as colloidal silver is in fact usually a combination of ions (dissolved), atoms (colloidal), crystals (suspended but usually settle out) and salts of silver (rarely dissolved and usually settle out). Soluable silver salts, like silver nitrate, provide free ions of silver but also dangerous nitrate ions!
The best bio-availability is from the ionic form, with rapidly decreasing biological benefits from the other forms, the ionic form being 300 times more effective to 17,000 times more effective then many silver salts! Put another way, you would need a daily dose of 1 to 50 gallons of "poor quality" Cs to equal a tablespoon of 5 PPM ionic silver!
Ion of silver - an atom, missing one (most common, monovalent) or more electrons. It has distinctly different properties then metallic silver and is actually in solution, and thus not colloidal. Carries a positive, ionic electrical charge, being short one or more electrons and thus very bio-active.
Atom of silver - the smallest particle of silver and it has a negative surface charge in a colloidal state. This charge is like a static charge, which has minor biologic benefits.
Crystal of silver - many silver atoms chemically bonded together. They may have a negative surface charge in a colloidal state but are usually too large (will continue growing) and will settle out.
Salts of silver - chemically bonded silver ions to other materials that were dissolved in the starting water. They are usually poorly soluable and thus form crystal growths and settle out.
nm = nanometer or billionth of a meter. 1/1,000 inch is roughly 25,000 nanometers!
A popular measure of the existance of a colloid, such as colloidal silver, (but not milk, which is also a colloid) is the Tyndal effect of "the dispersion of a light beam shown thru the liquid". A cloudy path of the light beam will be evident if there are colloidal particles in suspension! It is visible in colloids as weak as 0.1 PPM. Ions, the prefered form of silver, are NOT visible, even with a high powered microscope!
Thus, a strong Tyndal effect is an indication of larger silver particles and thus less bioavailability while a weak Tyndal effect indicates more ions of silver, assuming you are comparing the same PPM.
