Abstract

1,150,096. Treating cyanide wastes. TOYO INK MFG. CO. Ltd. 13 Sept., 1967 [14 Sept., 1966], No. 41134/66. Heading C1C. Effluents containing cyanides are treated with organic carbonyl compounds to eliminate the poisons. Ketones and aldehydes exemplified are acetone, methyl ethyl and methyl isobutyl ketones and cyclohexanone and formaldehyde, acetaldehyde and benzaldehyde, respectively. The products of the treatment may be further treated with air, HCl, NaOH or alkali sulphides.
