Abstract: The present disclosure relates to the technical field of wood preparation, and in particular, to a method and device for preparing a magnetic bamboo wood. A technical problem to be solved in the present disclosure is that: Lignin in a wood will affect the soaking efficiency of the wood during soaking of the wood. In the present disclosure, sodium hydroxide and sodium sulfite in a ratio of 2:1 are put into the soaking bucket in sequence through the high-precision powder weighing equipment and are fully dissolved in distilled water to obtain a solution, so that the solution reacts with the lignin in the bamboo wood to elute the lignin, which increases the porosity of the bamboo wood, improves the soaking efficiency, and improves the magnetism of the bamboo wood.
