Abstract:

In this experiment, Campanumoea javanica polysaccharide-iron (Ⅲ) complexes (CJP-Fe3+) were synthesized with
Campanumoea javanica polysaccharide and ferric chloride as substrates. The iron content of the complex was measured
by phenanthroline spectrophotometry and physiochemical properties, stability and reducing power were also investigated.
Its structural characteristics were analyzed by infrared (IR) spectroscopy. The CJP-Fe3+ complexes were obtained as a redbrown
amorphous powder with an iron content of 22.81%. Qualitative identification experiments showed that there was no
free Fe3+ detected in CJP-Fe3+ complexes. The complex was stable in the air and within a broad pH range from 3 to 12; the
structure of this complex in this pH range was not destroyed. Thus, CJP-Fe3+ can be developed as a new iron supplementary.

Key words: Campanumoea javanica polysaccharides-Fe3+ complex, physicochemical properties, iron supplementary
