Soil polluted with heavy metal ions is a serious environmental problem. Rabbit protein, prepared by reduction method C, had excellent adsorption performance of heavy metal ions. The adsorption mechanism of rabbit protein was studied and the adsorption process could be well described by the quasi-secondary dynamics equation. When the dosing quantity of rabbit protein powder was 50 g/l and the adsorption time was 180 min, the removal rate of Cu2+ reached 58.52%. Combining the zeolite powder and using the principle of electro spinning, the nano protein membrane was prepared to adsorb copper ion in the soil, which was efficient, low-cost, and achieved excellent adsorption effect. Hence it could be used as a new type of adsorption material to work out the pollution of heavy metals in the soil. Using waste to treat waste not only realized the reasonable use of a natural protein resource, but also had a certain practical significance on the safety of green organic food.
