Resumen

RIVAS, B.L.  y  PEREIRA, E.D.. OBTENTION OF POLY(ALLYLAMINE)-METAL COMPLEXES THROUGH LIQUID-PHASE POLYMER BASED RETENTION (LPR) TECHNIQUE. Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.1, pp.165-171. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000100020.

Poly(allylamine)-metal complexes with different metal ions (Co(II), Cu(II), and Ni(II) in conjunction with an ultrafiltration membrane were prepared. They were obtained varying the polymer/metal ion ratio and the pH (1, 3, 5, 7). The retention at pH 1 and 3 was lower than 10%. The study was carried out with the polymer-metal complexes obtained at pH 5 due to the high retention but not at pH 7 because Cu(II) precipitated. They were characterized by FT-IR, UV-Vis spectroscopy, thermogravimetric analysis, and intrinsic viscosity

Palabras clave : Poly(allylamine)-metal complexes; ultrafiltration membranes; intrachain complexes.
