METHOD FOR PREPARING SILICOTITANATE AND CS ADSORBENT |
| 摘要 |
The present invention provides a method for mass production of silicotitanate at low costs using SiO2; and a cesium adsorbent containing silicotitanate in which Na+ is substituted with H+ by acid treatment of Na-silicotitanate. The cesium adsorbent according to the present invention may be used in a filter for purification of air and water, and also as an agent for restoring soil, atmosphere and ocean contaminated with nuclide materials. |

1. A method for preparing silicotitanate comprising:
a first step of mixing SiO2, TiO2, NaOH and H2O at a molar ratio of SiO2:TiO2 ranging from 1.1:1 to 1.5:1; and a second step of hydrothermally synthesizing the mixture of step 1 at a temperature of 90° C. to 180° C. |
