Modified clinoptilolite as an ion exchange material

摘要

An ion exchange material for the removal of radioisotope cations such as the cations of caesium and strontium from an aqueous environment containing the radioisotope cation comprises a modified clinoptilolite produced by treating a natural clinoptilolite with sodium hydroxide at a concentration of approximately 2M or with hydrochloric acid at a concentration of from 0.1 to 5M for a suitable treatment time and at a suitable treatment temperature. The modified clinoptilolite is especially effective in the removal of radioisotope cations from an aqueous environment.
