Abstract
Polyamidoamine (PAMAM) dendrimer of G3.5 and G4. 0 were synthesized by divergent method. Effects of the polyamidoamine dendrimer generation, pH value of solution and reaction time to the complexation between Cu2+ , Co2+ and polyamidoamine dendrimer were studied in this paper. The results showed that the maximum absorbing wavelength of Cu2+/G4.0PAMAM dendrimer and Co2+/G4.0PAMAM dendrimer occurred blue shift in the presence of G4. 0 polyamidoamine dendrimer, but the G3.5 polyamidoamine dendrimer had seldom coordinated with Co2+. When increasing reaction time, the absorbency intensity of Co2+/G4.0PAMAM dendrimer enhanced, while the absorption curve of Cu2+/G4.0PAMAM dendrimer had hardly changed. The solution pH value had strongly influence on the complexation between Cu2+ , Co2+ and polyamidoamine dendrimer, which supplied theory base to recycle.关键词
