sulfosalicylic acid and Fe chelation
My goal is removal of all Fe ions in a plating bath (yes I am yet another obsessed PbO2 seeker) and sulfosalicylic acid was claimed to chelate or
otherwise trap free Fe ions. I am not familiar with this compound. A google search yielded nil on the synthesis. I do have salycilic acid, and my
gut tells me a bit of sulfuric is involved.
Anyone know anything about sulfosalycilic acid, or know of a way to remove Fe ions from a mildly acidic (nitric) plating bath? As always, TY

The stuff is cheap enough that synthesis would be academic, but I haven't found the synthesis described.
It is a common biomed reagent used in urine testing.
The iron can be removed by precipitation and this reagent is used for color testing a sample and detection of however complete was was the removal of
the iron via precipitation and filtering.

For larger applications, I would go with a strong acid (sulfonated styrene-DVB copolymer) exchange resin. It has a high capacity and is easily
regenerated.

Rosco and O3, thank you for the advice. As far as the sulfosalicylic acid, probably best to buy altho it would be an interesting synthesis.

Hmm, this is not something I am familiar with... more research is required! Thanks!
