What should I do wit it? - Old Chems

Well - I'm changing chemical stratagies; I have about 9L of used cucl2, and about 7L of Developer with a bit of life left. I've read that slowly increasing the PH of CUCL2 will cause the Copper to precipitate out. SO I was thinking I could mix _ in small batches, slowly, the developer with the Etch, to reach a ph of 9, Once this has exhausted the developer, I can use Lye, mixed with water in it's own process. TO fully exhaust the acid, I'll then slowly drip Muriatic, till it's PH 7, then let it safely evaporate down, Taking sludge to haz-waste facility. Does sound like a good plan? JT
