▎ 摘  要

NOVELTY - Repairing cadmium-polluted soil using graphene oxide reinforced Echinacea purpurea involves adding graphene oxide into the cadmium-polluted soil to be repaired, uniformly mixing, and planting Echinacea purpurea for realizing the removal of heavy metal cadmium (Cd) in the polluted soil. USE - Method for repairing cadmium-polluted soil using graphene oxide reinforced Echinacea purpurea for strengthening Echinacea purpurea. ADVANTAGE - The method uses graphene oxide as the enhancer, which improve the comprehensive accumulation effect of the purple pine nut to the soil Cd, promotes the reduction of Cd in the soil; and the echinacea purpurea as a flower plant also has the effect of beautifying the environment. The method is carried out under low cost, causes no damage to the physical and chemical properties of the soil, no secondary pollution and so on, and uses plant repairing technology as main body, assisted with exogenous strengthening measures, with good repairing effect, low investment, small workload, technical requirement is not high, and suitable for soil pollution repairing and ecological restoration of large area.
