Abstract

Process for recovering cyanuric acid from treated mother liquors from gilders, in particular to recover the cyanuric contents chosen between cyanuric acid and alkali metal salts thereof and mixtures of the above acid, isomers and salts present in solution in the effluent mother liquor resulting from the preparation of chlorinated isocyanuric acids and salts thereof, and from which the available chlorine has been separated; characterized in that it comprises contacting said effluent mother liquor with an alkali metal cation selected from sodium and potassium, in sufficient quantities to effect the precipitation of the cyanuric contents of the effluent mother liquor, at a ph of the order of 7 to 11.
