OBTENTION OF POLY(ALLYLAMINE)-METAL COMPLEXES THROUGH LIQUID-PHASE POLYMER BASED RETENTION (LPR) TECHNIQUE

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...
