Gentlemen,
My goal is not to collect and store Cu(OH)2, but rather reduce the
waste by removing the excess water. The reason for wanting to reduce
the waste is so that I do not have a large volume of chemicals on
hand, and do not have to make frequent trips to the hazard waste
facility. I can not see how taking a small amount of copper hydroxide
and contaminating a chunk of concrete and having it buried in a
landfill is benifical. Have you seen how they crush and grind
everything that goes into a landfill. Rather I would like to take it
to a hazard waste facility and have it properly dealt with. If I was
willing to have the copper dumped into a landfill and have it
eventually work it way into the water supply, I might as well pour it
down the drain. Once again thanks to everyone for the help.
