摘要：

The interaction between polyvinylpyrrolidone (PVP) and metal cations has been studied in absolute ethanol and water at room temperature and atmospheric pressure. The UV-VIS and IR absorption spectra of metal cations, PVP and PVP-Mn+ (Mn+ = Fe3+, Co2+, Ni2+) were given. It was shown that PVP and metal cations formed unstable complexes, and the coordination stability constants were determined according to the Miller-Dorough method. The stability constants of PVP-Fe3+ and PVP-Co2+ were lower than 10 and 0.6, respectively, and that of PVP-Ni2+ was too low to be estimated. The solid complexes of PVP,Fe3+ and PVP-Co2+ were also synthesized under proper conditions. (C) 2000 Elsevier Science B.V. All rights reserved.
