The Diphonix class of ion exchange resins is characterized by the presence of geminally substituted diphosphonic acid groups chemically bonded to a polymer matrix. Regular Diphonix contains gem-diphosphonic groups chemically bonded to a sulfonated styrene-divinylbenzene matrix. Modification of the properties of Regular Diphonix are achieved by the introduction of additional functional groups such as anion exchange groups in Diphonix-A and phenolic groups in Diphonix-CS. Diphosil has a silica matrix in which the gem-diphosphonic groups are chemically bonded to an organic polymer graft that surrounds the silica particles. Applications of the Diphonix resins range from treatment of a variety of radioactive waste to iron control in hydrometallurgy and semiconductor manufacture.
