ABSTRACT:
This invention relates to the purification of industrial effluents containing cyanide ions, and cyanide precursors like acetone-cyanohydrin. More particularly, the invention relates to the purification of such effluents by utilizing a complexing compound followed by treatment with an anion exchange resin and optionally cation exchange resin to remove the cyanide complexes. The cyanide values are recovered from the resin by acid regeneration.
