Silica having metal ions absorbed thereon and fabricating method thereof

摘要

A silica having metal ions absorbed thereon and a fabricating method thereof are provided. The silica having metal ions absorbed thereon is a silica having metal ions absorbed thereon and being modified with persulfate salt. The method includes following steps. A solution is provided, and the solution includes silica and persulfate salt therein. The solution is heated to react the silica with the persulfate salt, so as to obtain silica modified with persulfate salt. Metal ion source is added in the solution, the metal ion source dissociates metal ions, and the silica modified with persulfate salt absorbs the metal ions to obtain the silica having metal ions absorbed thereon.
