<p>A composite magnesium hydroxide containing a carbonate group and having a large BET specific surface area, a method for producing the same and an adsorbent comprising the same. The composite magnesium hydroxide is represented by the following formula (1) and has a BET specific surface area of 100 to 400 m 2 /g.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒMg 1-x M x (OH) 2-y (CO 3 ) 0 . 5y ·mH 2 O€ƒ€ƒ€ƒ€ƒ€ƒ(1)
(in the above formula, M is at least one divalent metal ion selected from the group consisting of Zn 2+ , Cu 2+ , Ni 2+ , Co 2+ , Ca 2+ , Mn 2+ , Fe 2+ and Ba 2+ , and x, y and m satisfy the following conditions:
0 < x ‰¦0.5
0.02 ‰¦y ‰¦ 0.7
0 ‰¦ m ‰¦ 1.)</p> |
