Once the patients receive hemodialysis treatment, they typically 20 mL blood due to filtration. Therefore, patients who receive regular hemodialysis treatment will lose approximately 20 g iron every year. And they are prone to iron deficiency, which in turn causes iron deficiency anemia. It is common to use iron pyrophosphate as a food additive to supplement iron. However, iron pyrophosphate is a compound of ferric iron, the efficiency of absorption for human body is worse than that of ferric iron. Therefore, we choose to synthesize iron phosphate of ferrous iron to improve the absorption rate, and make it porous to further improve the absorption rate. In this study, viviantie was synthesized by the reaction of ferrous sulfate and disodium hydrogen phosphate, and β-cyclodextrin was added as dispersant, successfully prepared the porous viviantie.
