| titleOfInvention | Bifunctional material for reduction and removal of chromium (VI) in water and preparation method thereof |
| abstract | The invention discloses a bifunctional material for reducing and removing chromium (VI) in water and a preparation method thereof. The structural feature of the material is that 13X molecular sieve grains (1~5 um) are embedded with Fe 3 O 4 nanoparticles (particle size 3~5nm, average particle size 3.8nm), Fe 3 O 4 The content is 5.0%~10.0%. The 13X molecular sieve in the present invention has very good adsorption performance for metal ions and impurities in water, and can cooperate with the reduction performance of Fe 3 O 4 . The combined effect of the above two factors endows the material with the function of efficiently reducing chromium (VI) in water and adsorbing its reduction product chromium (III), and the material is magnetic and easy to recover. The usage amount of Fe 3 O 4 is extremely low, and it is expected to promote the production and use on a large scale. |
