ABSTRACT:
Applicants have developed a unique process for preparing a shaped article comprising an ion exchange composition and a hydroxy oxide binder. The ion exchange compositions include metallotitanates, metallogermanates, pillared clays and metal phosphonates. The process involves combining the ion exchange composition with a binder precursor and water, forming the mixture into a shaped article and heating the article at a temperature of about 85.degree. C. to about 120.degree. C. These shaped articles are useful for removing metal ions such as cesium from feed streams.
