Description

technical field [0001] The invention relates to the technical field of adsorption materials, in particular to a C-Bi 2 o 3 -CuO-ZnO adsorption material and its preparation method and application. Background technique [0002] Porous activated carbon material has a unique skeleton structure, high surface area, directional pore distribution, and high chemical stability. It is a pollution-free and environmentally friendly adsorbent material. and other fields have been widely used. However, the adsorption and catalytic performance of a single porous activated carbon material is limited, and it cannot exert a good adsorption effect. Due to its unique properties, the composite porous activated carbon material has better adsorption and catalytic performance than a single porous carbon material. focus. [0003] With the development of industry, wastewater containing heavy metals has become a major problem for people. Heavy metals have significant toxicity to humans, animals and...
