摘要

The invention relates to a process for eliminating inorganic complex anions, containing an element from sub group 5, 6 or 8 of the Periodic Table of the Elements as the central atom, from waste waters or aqueous solutions containing these. The object underlying the invention is to provide a process by which such inorganic complex anions can be removed from waste waters or aqueous solutions avoiding the disadvantages of the known processes, for example the formation of toxic sludge, which poses land filling problems, in precipitation and flocculation processes or the requirement of having to use large amounts of chemicals. The latter also applies to flotation processes. The object is achieved according to the invention in that the anions are selectively separated off by sorption from the waste water or aqueous solution using an easily chemically regenerable aluminium oxide.
