Zusammenfassung

Mit Hilfe von Alamin oder besser Aliquat, gelöst z.B. in Toluol oder Tetrachlorkohlenstoff, kann Mangan(II) mit gutem Erfolg aus sauren Thiocyanatlösungen extrahiert werden. Mn ist in den organischen Extrakten als Mn(NCS) 2−4 enthalten.

Summary

Manganese(II) is efficiently extracted from acidified thiocyanate solutions by alamine and, even more effectively, aliquat dissolved in e.g. toluene or CCl4. The metal-containing species present in the organic extracts is Mn(NCS) 2−4 .
