Abstract:
11.0 for the pH of reaction solution,65℃～75℃for the reaction temperature,and 1:1.7 for the mass ratio of corn(dry weight)to FeCl_3?6H_2O.The corn polysaccharide-Fe(Ⅲ)complex synthesized with the optimized process was stable,with good solubility in water.The assay of Fe(Ⅲ)was 39.86%,40.20%and 40.17%,respectively for three batches of products.The RSD was
