Radioactive isotopes of iron, manganese, cobalt, zinc, and cadmium can be separated in carrier-free form from the cyclotron target metals by continuous electrophoresis (1022). Traces of iron, zinc, copper, and mercury in gallium can be detected on paper using ethylene diaminetetraacetic acid or tartaric acid as complexing agents (691).…”
