Embodiment 1
[0041] (1) 27.05 gFeCl 3 ·6H 2 O was added to 39.2 ml deionized water to prepare 2 mol / L FeCl 3 solution, heated and stirred in a water bath at 80 °C for 1 h;
[0042] (2) Prepare the NaOH solution of 6 mol / L, add the prepared NaOH solution dropwise to the FeCl prepared in step (1) 3 In the solution, reddish-brown flocs will be produced subsequently, and after the pH value of the solvent in the reddish-brown flocs is above 11.2, stop adding the NaOH solution dropwise;
[0043] (3) Take wood chips and crush them, and then sieve the crushed wood chips to get wood powder with a size between 20-30 mesh;
[0044] (4) Dissolve 5 g of sawdust powder prepared in step (3) in a mixed solution of 40 ml deionized water and absolute ethanol (by mass ratio, deionized water: absolute ethanol = 3:1), and add After 2 g of isopropanol, 5 g of glacial acetic acid and 5 g of NaOH (granular), stir at room temperature for 3 h, then sonicate for 1 h, and finally stir in a water bath at 80 °C for...
