| description | 1403253 Treating waste water to remove metal ions SANKYO KASEI CO Ltd 14 Aug 1972 [18 Aug 1971] 37756/72 Heading C1C Waste water containing metal ions having a standard electrode potential of at least -0À44 V (at 25 C.) is treated to remove said ions by the addition thereto of at least one mercaptos-triazine and water-soluble salts thereof. The triazine has the formula wherein R is -H, -NH 4 , C 1-8 alkyl or alkoxy, phenyl, cyclohexyl, morpholino, phenoxy, -NR1 2 or SR11, R1 being -H, C 1-8 alkyl, phenyl, cyclohexyl, naphthyl or benzyl, R11 being C 1-8 alkyl, phenyl, cyclohexyl, naphthyl or benzyl, m is 1 to 3, n 0 to 2 and when n is 2, each R may be the same or different. Alkali metal, alkaline earth metal and ammonium salts of mercapto-s-triazine, may be used. Exemplified treatments are directed to waste fixing solutions, waste electroplating solutions, and solutions containing Cu++, Cd++, Pb++, Hg++ and Ag++ ions. |
