In this study,pot experiments were utilized to investigate the impact of 3D electric fields on the efficacy of Macleaya cordata in remediating uranium-contaminated soil.The results indicated that compared with the 2D electric field,the coupling between the 3D electric field and Macleaya cordata could lead to an increase in uranium mass fraction in both the above-ground and underground parts of Macleaya cordata by 17.14%and 43.3%,and an increase in dry biomass by 40.4%and 37.6%,respectively.Additionally,the proportion of exchangeable uranium...
