Abstract
PURPOSE: To remove heavy metals or sulfuric acid radical present effectively by treating adsorbents of alumina-supported titanium oxide or alumina support alone by hot water containing nitric acid or ammonia.
CONSTITUTION: Adsorbents of alumina alone or alumina-supported titanium oxide are treated with hot water containing ammonia to remove sulfuric acid radical present, and also the adsorbents are treated with hot water containing nitric acid to remove heavy metals such as iron, etc. If necessary, both the operations are performed in combination. In case where the alumina support is pretreated, titanium oxide is supported on the alumina support after the pretreatment.
