Abstract
Starting from the principles of sol-gel method, developed originally for the preparation of nuclear fuels in spherical form, their application to the preparation of microspheres of various non-nuclear elements is presented. In addition to the preparative conditions of the primarily hydroxidic spheres, their conversion into other insoluble compounds such as phosphates, ferrocyanides, sulphides, etc. is described. These sol-gel products work very well as ion-exchangers; their sorption properties are quite comparable to those of the common powder sorbents, the sphere from being their main beauty. Applicability of these sorbents as well as their limitations are also discussed.
