| abstract |
Disclosed is an lron(lll)-based phosphate adsorbent comprising: i) an adsorbent base material which is starch; ii) polynuclear iron(III) oxide hydroxides; iii) a soluble carbohydrate which is a glucose derivative, partially incorporated into the polynuclear iron(III) oxide hydroxides; and iv) optionally, a carbonate; wherein the iron(III)-based phosphate adsorbent has a phosphate binding capacity of at least about 140 mg adsorbed phosphate by 1 g of phosphate adsorbent, and wherein said iron(III)-based phosphate adsorbent is isolated by spray drying. Also disclosed are methods of preparation. |
