| 摘要 |
A novel composition including an inorganic mixed metal oxides and partially hydrated oxides exhibiting anion exchange properties and a method of preparing the exchanger composition by coprecipitating hydroxides or hydrated oxides of a pair of metal elements such as aluminum and titanium, drying the mixed metal hydroxides or hydrated oxides, exchanging the anion of the mixed metal hydroxide or hydrated oxide for a nonvolatile anion such as a sulfate anion and calcining the mixed metal hydroxide or hydrated oxide to form a mixed metal oxide or partially hydrated oxide exhibiting anion exchange properties.
