a novel phenolic type polymeric bisazacrown pseudo ether PACE were synthesized by methods of first polymerization then functionalization and Na+ template-guided.Series synthetic reactions were studied using FTIR spectra method for tracking monitor.A best experimental formula of phend-aldehyde crosslinking reaction using monomer phenoxyethanol and a better conditions of series substitution reactions on the phenolic aldehyde parent polymer were achieved.FTIR spectra data of polymers of a series were achieved also.Polymeric static adsorption properties for normal metallic ions were tested.The results showed that the polymer has good adsorption properties for K+
Na+
Hg2+
Cd2+
Fe3+
Pb2+
Cu2+ and the capacities of adsorption were 1.43
0.98
1.84
0.68
0.79
0.61 and 0.57 mmol/g-r
respectively.By FTIR spectra method
a preliminary discussion on adsorption mechanism was given in this paper.The results showed not only —CH2OCH22—and PhOCH2—and —CH2NCH2—
could chelate metalion
but also —CH2OH did to a certain extent in the above mentioned complexes.There is slow oxidation-reduction in the adsorption of Hg2+ on PACE and the —CH2OH in the polymer PACE was oxidized to —COOH and Hg2+ were reduced to Hg2+2.
