Manufacturing method for fluorescent transparent magnetic wood

[0032] Embodiment 1: The preparation method of a kind of fluorescent transparent magnetic wood described in this embodiment is specifically carried out according to the following steps:

[0033] 1. Wood delignification:

[0034] Immerse wood with a thickness of 0.1mm-20mm into a reactor filled with a sodium hypochlorite solution with a concentration of 0.1mol / L-10mol / L to obtain a reaction system, then add glacial acetic acid to adjust the pH of the reaction system to 1-7, and seal the reaction Put the reactor at a temperature of 70°C to 200°C, cook for 1h to 52h, cool to room temperature, and then add hydrogen peroxide with a concentration of 0.1mol / L to 10mol / L into the reactor. Under the condition of ℃~200℃, continue cooking for 1h~52h, cool to room temperature, take out the reacted wood, and under the condition of 50℃~200℃, vacuum dry the reacted wood for 1h~52h to obtain Lignin wood;

[0035] The volume ratio of the hydrogen peroxide having a concentration of 0.1mol / L t...

[0055] Embodiment 2: This embodiment is different from Embodiment 1 in that the wood described in step 1 is coniferous or broad-leaved. Others are the same as in the first embodiment.

[0056] Specific embodiment three: the difference between this embodiment and one of specific embodiment one or two is: step 2 described in 4. contains Fe 3+ The salt of ferric chloride, ferric sulfate or ferric nitrate; Step 2 described in 4. contains Fe 2+ The preferred salt is ferrous chloride, ferrous sulfate or ferrous nitrate. Others are the same as in the first or second embodiment.
