Well, I already know the procedures with the cucumber jar and hydrochloric acid in all its variations. I also know the page the user Jmac sent me but it does not contain any help or answer to my specific question (but thanks anyway!).
But what I am trying to do is called "chlorite peroxide sulfate process".
And I don't want to advertise the manufacturer (but if anyone wants to know the manufacturer, he can contact me via PM here over the forum if this is possible). But after 3 more attempts and very (very) much research I can report the following;
One have to dilute the 25% sodium chlorite solution. And very strongly. So the latest thing I tried was this;
100 ml of distilled water
1 ml sodium chlorite solution
0.14 gram penta potassium
2.66 gram sodium peroxodisulfate
I put the water in a 100 ml amber glass bottle and added the penta potassium to make it more alkaline. Then I added the sodium chlorite solution and after 3-5 minutes the sodium peroxodisulfate powder. Then I waited 90 minutes.
As a result this time I really got chlorine dioxide but only a very weak solution this time. So I would need the exact dosage for a 100 ml bottle of CDS after the "chlorite peroxide sulfate process" with the above mentioned ingredients.
But I'm already close to it, so I tested the last attempt by myself. And like I said before; it looks and tastes really after CDS but only super super weak. So, still nothing useful...
Why I want to do it this way and not different because I find it easier to just weigh a little bit of powder in advance and then if I need it wait 90 minutes and then I have fresh CDS in best quality and also for a great price. But what kind of money is earned with CDS I don't have to mention here. In any case I want to save money and just replicate what I used to buy.
So if anyone knows about it; thanks for the help in advance!
