Abstract: The present invention relates to layered multi-metal-oxide-based magnetic biochar and a preparation method and use thereof. The preparation method includes: S1. mixing biomass and an iron salt solution for impregnation, and then adjusting a first pH value of a solid phase material after solid-liquid separation to obtain pretreated biomass; and S2. pyrolyzing the pretreated biomass to obtain magnetic biochar, then mixing the magnetic biochar with a solution containing at least two metal salts and adjusting a second pH value, and then performing hydrothermal treatment to obtain the layered multi-metal-oxide-based magnetic biochar. The obtained layered multi-metal-oxide-based magnetic biochar has a large specific surface area, magnetic properties, a layered morphology, and strong adsorption capacity, and can be applied to the treatment of arsenic- and cadmium-containing composite contaminated water bodies, and also to arsenic and cadmium passivation in farmland soil, thereby reducing health risks of crops in the food chains, and ensuring food safety.
