Cation-exchange separation of copper from zinc, nickel and lead

Cation-Exchange Techniques in Radiochemistry

“…With 2 % i;a:!0 Cu is eluted before Co and Ni (49). Cu is eluted before Zn, Mi and Pb with 0.5 M ammonium acetate (705). 2+ Cu formiS a much more stable EDTA chelate than Mg, Sr and Ba and could therefore be separated from these ions by elution with EDTA on a Zerolit-225 column (91).…”
