A. Hi Marisol Rosel, I don't know if you have the Copper sulfate as a salt or as a solution. If you have it every bit common salt, I recollect it'due south quite easy, there'south from chemical betoken of view no reason why it should elapse, peradventure for auditing purposes you should sample the batch, extensively test on the important parameters and requalify it as "proficient". The only thing is that, if it's however in the original package it could have additional moisture in information technology. If that's no option, I'm sure you lot will find an interested tertiary party who will buy (or take it for free) from you, even if information technology'south "expired". Look for electroplating shops in your surface area, they may want to take it. I don't recommend to contact the agronomics companies, as the origin of the copper sulfate and storage atmospheric condition are unknown to me. If it's liquid, you lot can just go for electroplating the Cu out, until you accept depression Cu in the liquid (< 200 mg/l.) then for the remaining part apply selective ion exchange to remove the Cu and finally neutralise the remaining liquid and you can dispose it of. Sounds piece of cake, simply ways a lot of piece of work and experience and if you're not already having the right equipment and people in house, amend leave it. In that case you improve endeavour to detect an outside company who wants to do this job for you, but exist prepared for tough negotiations (the Cu value is already considerable then don't allow them pull you a leg) and in Western Europe we tin can -fortunately- merely use registered companies with a proven practiced track record and an allowance for that specific activity. All-time regards, Harry. Harry van der Zanden - Budapest, Hungary A. Marisol, Copper sulfate does not go bad, or elapse in the sense that information technology is no longer useful. You should try to sell information technology to any of a number of companies, including companies that brand agricultural chemicals, electroplating chemicals, or fifty-fifty animal food supplements.
