Potassium Permanganate disposal

[christian_cowgirlGSR]

I have some potassium permanganate I'd like to use to dip some plants in (to prepare them for shipping - to make sure there aren't any snails on them and to "sanitize" them). Can anyone tell me how to properly dispose of it once I've used it? Would it be bad to dump it down the drain, considering that I have a septic system?

You can neutralize it with H2O2 first though a little bit diluted down the drain should not harm your septic bacteria

It stains skin (and other things) and burns soft tissue, so be careful. Eye protection is highly recommended.

I don't know that I would pour it down the drain, not because of any hazard, but because it could stain your sink. In the quantity you're talking about, if you dilute it with water, disposal isn't a problem. I would probably dilute it and place it in the sun for a day and then after it decomposed, pour it outside on the ground away from any water sources.
