Abstract
Aluminum hydrogels which are stabilized at pH below 7 with a polymer containingcarboxyl groups, e.g., carboxy methyl cellulose or gum arabic. The gels are useful as phosphate binding agents in the treatment of hyperphosphatemia. Such polymers are incorporated during the formation of the aluminum hydrogel, permitting a high yield to be obtained, and preventing colloidal sol formation during exchange with monovalent anions.
