Synthesis and characterization of a new soluble soybean polysaccharide-iron(III) complex using ion exchange column.

Abstract:

:A new ion exchange column method was investigated to synthesize the soluble soybean polysaccharide-iron(III) complex (SSPS-FeIII1) using soluble soybean polysaccharides (SSPS). The feasibility of ion exchange column reaction was explored firstly. Results indicated the D730 anion macroporous adsorption resin could effectively absorb SSPS and the static adsorption saturation time was 20h. The iron content of the complex reached up to 15.07% when trisodium citrate concentration was 2mg/mL. The structure of SSPS-FeIII complex synthesized by this method (SSPS-FeIII12) was compared with that prepared by trisodium citrate - ferric chloride method (SSPS-FeIII23). UV-vis absorption spectra, FI-IR spectra and XRD patterns confirmed that both hydroxyl groups and carboxyl groups in SSPS were involved in the coordination reaction and the iron core of SSPS-FeIII1 was a polymerized β- FeOOH structure. Those results indicated that the ion exchange column method could effectively prepare the SSPS-FeIII complex.
