"rejuvenation" of potassium permanganate

Potassium permanganate is known to be used at the discoloration process of jeans . A way of application is by impregnating pumice stones in a potassium permanganate solution and after that remove the pumice and let them dry . In this way pumice stones "encapsulate" an amount of permanganate and can be used to "stonewash" jeans and diminish the shade of jeans at the same time . This application results in a fashionable effect . As a result we get an inormous amount of pumice stones having a brown shade.(This is the inactivated form of potassium permanganate, magnesium oxide). Is it possible to "rejuvenate" the pumice? Is it possible to regain some of the quantity of permanganate by "oxidation" of the magnesium oxide?

Although potassium permanganate is made from manganese dioxide, the process would require that the MnO₂ was extracted from the stones. My guess is that this would not be economically viable. However, the stones could be re-impregnated with potassium permanganate to recharge them.

Misspelling ?

Down in hazards there is a sentence "such as a powder mixture of KMnO4" is it supposed to be powder? im not good with science so i didn't want to change it and find out powder meant something.

No KMnO4 does not come in the form of a powder, in fact it exists in form of dark voilet crystals.

Edit suggestions antidote topic

I decided to erase headline no 5 "As an antidote" because the information stated is not backed up by any references at all. The text said: "Potassium permaganate's use as an antidote for opium and specifically morphine overdose has been described in medical literature". Furthermore to my knowledge KMnO4 is not used as an antidote against any intoxicants. I know it used to be listed as an antidote agent (at least in sweden) against phosphorus, but this is no longer the case. -If it indeed is being used/misused outside of hospital settings somewhere for antidote reasons then I think it could be mentioned in the article, but then the claim would have to be backed up by quotation(-s) (and explain that it is equally effective as horse manure at combating opioid intoxication). /Chris 15:35, 08 October 2012 CET — Preceding unsigned comment added by 79.102.1.31 (talk)

Merger proposal

There's a section in this article entitled "Medical Uses" (a subheading in the "Uses" heading) that contains a link to a second article entitled "Potassium permanganate (medical use)" (https://en.wikipedia.org/wiki/Potassium_permanganate_(medical_use).

While the second article does add important information, it repeats some the information already in this article, and it's lacking in key technical details that are already in this article. It also contains a subheading entitled "medical uses", which is already the title of that article. That just adds to the confusion.

The second article seems redundant and potentially confusing to the reader.

Unless there are objections, I propose merging the other article into this one. For simplicity it might make sense to just create a dedicated "medical uses" heading, then bring everything over from the second article, and delete extraneous information that is already mentioned elsewhere here.

I'll give this a try. Will post an update on progress. Betsy Rogers (talk) 22:44, 21 October 2023 (UTC)[reply]
