| titleOfInvention |
Selective adsorbent for ammonuim ion and ammonia and preparation thereof |
| abstract |
A selective ammonium ion adsorbent prepared by introducing ion-exchangeable alkali metal ions into a double oxide of silica and alumina with a specified composition, which can selectively adsorb ammonium ions and ammoniacal nitrogen not only in fresh water but also in seawater without affecting other components while minimizing the variation of the pH value of seawater. It is useful also as an ammonia gas adsorbent. |
