specific Embodiment approach 1
[0032] Specific embodiment 1: The method for preparing fluorescent transparent magnetic wood described in this embodiment is specifically carried out according to the following steps:
[0033] 1. Lignin removal from wood:
[0034] The wood with a thickness of 0.1mm-20mm is immersed in a reactor containing a sodium hypochlorite solution with a concentration of 0.1mol / L-10mol / L to obtain a reaction system, and then glacial acetic acid is added to adjust the pH of the reaction system to 1-7, and the reaction is sealed Place the reactor at a temperature of 70℃~200℃, cook for 1h~52h, cool to room temperature, and then add hydrogen peroxide with a concentration of 0.1mol / L~10mol / L to the reactor at a temperature of 70 Under the condition of ℃~200℃, continue to cook for 1h~52h, cool to room temperature, take out the reacted wood, under the condition of 50℃~200℃, vacuum dry the reacted wood for 1h~52h to get stripped Lignin wood
[0035] The volume ratio of the hydrogen peroxide solution w...
specific Embodiment approach 2
[0055] Specific embodiment two: this embodiment is different from specific embodiment one in that the wood described in step one is coniferous or hardwood. Others are the same as the first embodiment.
specific Embodiment approach 3
[0056] Specific embodiment three: The difference between this embodiment and specific embodiment one or two is: the content of Fe described in step two ④ 3+ The salt is ferric chloride, ferric sulfate or ferric nitrate; the step 2 ④ contains Fe 2+ The salt is ferrous chloride, ferrous sulfate or ferrous nitrate. Others are the same as the first or second embodiment.
