A kind of magnetic Fenton-like catalyst based on chitosan and its preparation method and application |
| abstract |
The invention provides a magnetic Fenton-like catalyst based on chitosan and a preparation method and application thereof. The chitosan is dissolved in an acetic acid solution, manganese salt, iron salt and ferrous salt are added and stirred to obtain a uniformly dispersed Salt solution A, sodium hydroxide and sodium acetate are dissolved in water to form alkaline solution B; the salt solution A is added dropwise to the alkaline solution B at a uniform speed, and after the dropwise addition, the obtained mixed solution is placed in a constant temperature oscillator to vibrate and age to obtain CH-Mn-Fe gel beads; the CH-Mn-Fe gel beads are washed to neutrality, and freeze-dried to obtain a magnetic microsphere MnO 2 ‑Fe 3 O 4 /CH composite catalyst with a porous structure. The agglomeration of metal particles is avoided, the loss of metal is suppressed, the recovery is extremely easy, and the preparation process is simple. |
