I tried this methods before. It works, but yields are not so great but ok.
I got 2,5g - 3g sulphate from 5g P2NP
I used lead plates, cut from roofing lead. You have to use clean, blank surface on your electrodes.
Using porous clay pot for seperating your anode/cathode compartments works fine.
Anode compartment has to be filled with 12N sulfuric acid aswell.
Yes your mixture gets red. you have to remove it with non polar washings before basification.
What is important is temperature. in the paper it says not exceeding 40°C, but i experienced that this is too high.
Try to run it as cold as possible. Running your cell in an ice bath is an option. 10°C is prefered. and at the end you will see, that you just have a slightly red color. (less impurities, higher yield).
I tried this with max 10g P2NP, because my cell was that small. scaling up could be a problem because of heat generation.
You have to be creative in terms of active cooling than.
Trying this in a bucket with a big unglazed flowerpot would be awsome.
Maybe i will come up with a detailed procedure in future. unfortunately i cant provide pictures, because i tried this years before.
But hey, it is easy, non toxic and you need just common chemicals. But it takes time. you have to run your cell maybe for days, when you go large scale.
