| abstract | 1351918 Removing heavy metals MITSUBISHI CHEMICAL INDUSTRIES Ltd 27 Nov 1972 [30 Nov 1971 18 Dec 1971 13 Jan 1972 22 Feb 1972] 54755/72 Heading C1C [Also in Division C3] Heavy metal ions are removed from aqueous solutions with chelating polymers obtained by reacting compounds having two or more acrylyl groups with amino acids having two or more active hydrogen atoms bonded to nitrogen. In examples chelating polymers are obtained in reactions wherein the acrylyl compounds are methylene bisacrylamide, hexahydro-1,3,5-triacryloyl-s triazine and ethylene-glycol diacrylate and the amino acids are glycine, #- alanine, L-glutamic acid, L-lysine monohydrochloride, ornithine hydrochloride, L-lysine monohydrochloride and α - alanine; some of the polymers contain unreacted acrylyl groups and these are further reacted with hexamethylene diamine, 2-amino-ethanethiol, benzyl trimethylammonium hydroxide, ammonia and acrylamide; the polymers are used to separate copper ions from aqueous solutions. |
