Modified clinoptilolite as an ion exchange material. |
摘要 |
<p>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 0,1M 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.</p> |
