Nozaki, Toru published the artcileComplex formation of nitrilotris(methylene)tris[phosphonic acid] and flotation with the complexes, Recommanded Product: Dodecylamineacetate, the publication is Nippon Kagaku Kaishi (1988), 1017-20, database is CAplus.
From the polarog. behavior of Cu(II), Pb(II), Cd(II) and Mn(II) in nitrilotris(methylene)tris[phosphonic acid] (NTMP, H6L) solutions at an ionic strength of 0.4 adjusted with sodium perchlorate, the species of the metal complexes and their stability constants were determined In the pH ranges from 3.4 to 4.9 for Cu, 3.5 to 4.5 for Pb, 4.5 to 5.0 for Cd and at pH 5.6 for Mn, the species of MH3L–, MH2L2- and MHL3- were ascertained and the logarithms of their overall stability constants at 25¡ã were determined Flotation of NTMP by complexing with Fe(III) and the NTMP complexes of Cu(II), Pb(II), Cd(II) and Mn(II) was investigated in a cell (20 ¡Á 2.7 cm I.D.). Recoveries of 4.0 ¡Á 10-4 mol/dm3 of NTMP and 1.6 ¡Á 10-4 mol/dm3 of the NTMP complexes were 100%, and 98.8, 97.9, 92.8 and 81.2%, resp., by using 1.2 ¡Á 10-3 mol/dm3 of dodecylammonium acetate (DAA) for the former and 8.0 ¡Á 10-4 mol/dm3 of DAA for the latter, as surfactant at pH 7.0. 1420 Ppm of Cl–, 196 ppm of SO42- and 3100 ppm of NO3– did not interfere with the flotation. It seems that the flotation of NTMP and the complexes proceeds through the formation of the ion pair Rn?MHi?L, where n? = 6-n–i?, and R and n denote the cation of DAA and the charge of the metal, resp.
