| titleOfInvention | A gelatin-based hydrogel adsorbent for adsorbing hexavalent chromium ions and preparation method thereof |
| abstract | The invention discloses a preparation method of a gelatin-based hydrogel adsorbent for adsorbing hexavalent chromium ions, which comprises the following steps of: ultrasonically dispersing gelatin into deionized water at 45°C to 60°C, the ultrasonic dispersion time is 10 min, adding an appropriate amount of The oxidized multi-walled carbon nanotubes were sonicated for 1 h. Then it was poured into the forming mold, and after the mixture of gelatin and oxidized multi-walled carbon nanotubes was completely in a gel state, the obtained gelatin-oxidized multi-walled carbon nanotube gel was immersed in the pyrrole solution for 30 min, and the temperature was maintained at 0‑4℃. Add 30 ml of oxidant solution (8 g of ferric chloride hexahydrate dissolved in 100 ml of deionized water and 0.3 M hydrochloric acid) and keep for 8 h. The gel was washed again with acetone and deionized water, and dried to constant weight at 60°C. A gelatin-oxidized multi-walled carbon nanotube-polypyrrole hydrogel was obtained. In addition, the method has simple operation and low cost, and can be popularized and produced on a large scale. |
