<p>Aluminum silicate having a large cesium ion adsorption capacity and a production process therefor.
(1) The aluminum silicate is represented by the following formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒxNa 2 O·Al 2 O 3 ·mSiO 2 ·nH 2 O€ƒ€ƒ€ƒ€ƒ€ƒ(I)
(wherein 0.12 ‰¦ x ‰¦ 1.3, 5.0 ‰¦ m ‰¦ 15.0, and 5 ‰¦ n ‰¦ 15),
(2) the Na 2 O content of the aluminum silicate is 1.5 to 11.0 wt%, and
(3) at least 50 % of aluminum atoms are tetra-coordination aluminum atoms.</p> |
