血液透析是慢性腎臟病第五期患者,因腎功能喪失而必須接受的一種治療方式。而在每次病患進行血液透析時,會因過濾而損失約二十毫升的血液,所以病患在接受血液透析治療的同時,每年會損失約二公克的鐵。因此接受血液透析治療的病患容易缺鐵,進而造成缺鐵性貧血。 市面上常見將焦磷酸鐵作為食品添加劑用以補充鐵,但因焦磷酸鐵為三價鐵的化合物,人體吸收的效率較二價鐵的化合物差,故我們選擇合成同樣是鐵磷酸鹽,但是二價鐵化合物的藍鐵礦作為鐵劑以提高人體的吸收率,並將其顆粒孔洞化以進一步提高人體吸收的效果。 本研究利用硫酸亞鐵和磷酸氫二鈉反應合成藍鐵礦,並加入β-環糊精作為分散劑及發泡劑,成功製備出多孔洞的藍鐵礦顆粒。
Hemodialysis is a treatment for the patients with the fifth stage of chronic kidney disease because of the loss of renal function. 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.
