zinc sulphate disposal

[ktrezise]

How does everyone dispose of their zinc sulphate waste since it is toxic to aquatic life? (I have 0.1M solution )

[tigger]

I put it in my heavy metal waste. It is collected by an authorised company to be disposed of.

I pour stuff like that, especially when it's only 0.1M, into an ice cream container and let it evaporate quietly for a while on a shelf in my chem store. That way I end up with much less volume to fill up my heavy metal waste bottle with.

cheers...will do.

I evaporate it as much as possible then put it asdide for use when they make electrical cells with concentrated copper and zinc sulphate solutions.
