| titleOfInvention | Method for producing metal element adsorbent |
| abstract | (57) [Summary] [PROBLEMS] When a column is packed and waste liquid treatment is performed, A metal element adsorbent that hardly collapses, does not increase pressure loss, and increases the processing speed of waste liquid is obtained. After incinerating the adsorbent after the waste liquid treatment, no alkali metal remains as a residue, and thus the amount of waste does not increase. SOLUTION: NaOH, KOH or L having a pH of 7 to 10 The condensed tannin powder is dissolved in an aqueous solution of iOH, and an aqueous aldehyde solution or hexamethylenetetramine is mixed with this solution and heated to produce a gel composition. The stabilized gel composition preferably has a concentration of 0.01 N or more and 2 N or more. Contact less than nitric acid, hydrochloric acid or sulfuric acid. Thereby, Na, K or Li, which is a terminal atom of the molecule of the gel composition, can be changed to H atom. |
