    Selenium Disposal

    Guys, I have some stale Selenium to dispose of?

    What do you do with expired/exhausted Selenium – either neat solution or working strength?

    The literature warns about not pouring it down the drain – but gives no other clues to its disposal

    Thanks

    Martin

    Not sure about your location, but in the states and specifically here, the local dump has a couple days a year that you can bring hazardous chemicals for disposal without extra charge.

    put it in a tray and drop some old test prints into the solution and let them sit there for a week or so and it will dilute the solution even more until it is basically gone

    If you use it till exhaustion there won't be a lot of selenium in it. So as already suggested, you can pass some old test pritn through it. But here the problem may be silver salt, but you can also recover them.

    What is the dilution of this dilution (a delusion?)

    I don't know because I don't do it. However, some persons do use it on lawns, plants, etc. It is an ingredient in many fertilizers. Not a delusion at all.

    I hope it's not used on any edible plants, considering it's a toxic heavy metal.

    You need to brush up a little.. it's not a heavy metal, its not even metal actually (sort of a semi mineral/metal), and it isn't toxic in small quantities, in fact it is needed for cellular function, even in your own body.
