Abstract:
A kind of novel hydrophobic dendrimer containing plenty of N functional groups was synthesized with ethylenediamine as center core,methyl acrylate as branch monomer and 1,2-octenoxid as terminated functional group by the divergent method.The molecular structure of PAMAM-1,2-octenoxid dendrimer was characterized with FTIR,1H NMR,13C NMR and the results agreed to design.This dendrimer could dissolve in chloroform but not in water and cyclohexane.PAMAM-1,2-octenoxid dendrimer was used as the carrier in emulsion liquid membrane and the effects of PAMAM-1,2-octenoxid dendrimer concentration,Span-80 concentration,pH value in external aqueous phase,hydrochloric acid concentration in internal phase,Cd2+ concentration in external aqueous phase and the ratio of oil-interior(Roi)on the transport rate of Cd2+ were investigated.The results showed that transport rate of Cd2+ could reach above 99.1% under the optimum conditions of 3% PAMAM-1,2-octenoxid dendrimer,4% Span-80,2% liquid olefin,91% chloroform,1.0 mol·L-1 hydrochloric acid in interior phase and pH 7.0 in external aqueous phase.So PAMAM-1,2-octenoxid dendrimer could be used as a novel metal ions carrier.
