A reliable method for accurately detecting when either the steel wool in a recovery vessel exhausts or insufficient ferrous-ferric oxidation occurs, entails the use of a conventional electrochemical sensing cell. The cell, which is responsive to the ratio of ferric to ferrous ions in the solution, senses and presents a display relating to changes of that ratio as either of the aforementioned problems are encountered.

As you can see from the picture above, the roots turned out very good.. just a tad yellow, but I plan on toning it several times. I dried my hair and moved onto bleaching the top of my hair. For the top of my hair, I decided to try the . I used the measuring cup in the Ion Bleach to measure both products. I used 1 cup of bleach and 1 1/2 cups of developer. The consistency of these products together is very creamy and easy to work with. I found the coverage to be excellent and I ended up not using that much product. The bleach did not dry out at all. I left this product on for 50 minutes (checking after 30 minutes) and I wished now that I would have waited maybe 20 more minutes. My scalp still did burn with this Ion developer, but not as bad as it usually does. I rinsed and washed my hair with my new , towel dried my hair and then applied the Wella Frosty Ash toner with Clairol Pure White 30 volume developer (on damp hair) . I left that on for 20 minutes, rinsed then applied a mixture of both my conditioner and Clairol Shimmer Lights Conditioner (toning), left on for about 5 minutes, rinsed and then applied the to seal in my color. I love how my hair turned out.. still a little yellow on the roots to work on with 2x weekly shampoos of the Rene Furterer Silver Shampoo, but very good, indeed!
The regeneration of a used bleach-fix solution where the bleaching agent is a ferric salt of an amino polycarboxylic acid and the spent solution comprises silver ion and ferrous ion, may be carried out in a number of manners for purposes of the invention. FIGS. 1 and 2, two of the more common techniques, illustrate the more important steps. In FIG. 1, developed photographic elements on a web 5, are passed through a bleach-fix processing tank 10 where silver is removed from the elements by the action of the bleach-fix solution as previously described. Thereafter the used solution is passed in series through a silver recovery vessel 20 for removal of silver, an oxidation tank 30 for conversion of ferrous ions in the solution to ferric ion. Regenerated solution Y, may now be either recycled with regenerator solution to bleach-fix tank 10 or stored as shown.
