I am using ferric chloride bleaching solution,
But one day, this element became unavailable on the Egyptian market for unknown reasons.
- I inquired, and a friend advised me that it could be replaced by a ferric sulfate component, and I went and asked this inquiry to the late great teacher (Ron Mawry), just a few weeks before his death. Rather, it is probably the last question I brought to it.
The man said, “In theory, this solution can work with ferric sulfate, but it needs a lot of chemical calculations, etc. in order to calibrate the right amount.” (The response has ended.)
- I went and bought half a kilo of ferric sulfate element and the deal was never cheap, and when I tried to strive to prepare the bleaching solution with the same recipe while replacing the ferric chloride element and adding ferric sulfate instead of it, the idea did not work and I got a heterogeneous solution And it causes deposits on the second day of preparation, and when I tried it on a film roll, it was very strong and caused the destruction of most of the pigments and the emulsion became crimson light in color.
After that I was able to get ferric chloride again and it became very easy to prepare the bleaching solution,
But I had bought half a kilo of ferric sulfate and it was somewhat expensive, and I want to take advantage of this element as this is a waste of a little money.
- I want to know, in practice, has someone ever prepared bleach solution with ferric sulfate before?
How can I find an expert chemist to help me calculate the right amount.
God bless you all
