Abstract
The abundance of metal ions in galvanic waste solutions enables these solutions to be used for recovery of metals as well as complexing agen ts such as citrate and tartrate. The addition of oxalic acid to soluti ons containing complexing agents precipitates pure metal oxalate or mi xtures of metal oxalate and tartrate or citrate, the product depending on pH and concentration of components. The addition of oxalic acid to the rinsing bath after electroplating precipitates the most of the me tals such as Cu(II), Zn(II) and Pb(II).
