Experimental study of 3D electric field enhanced Macleaya cordata phytoremediation of uranium-contaminated soil
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 in the soil showed an increase of 10 percentage points.Meanwhile,the subcellular distribution of uranium within Macleaya cordata was altered,leading to increased uranium accumulation and transfer to organelles,particularly in the stems.These findings indicate that the 3D electric field can further improve the remediation performance of Macleaya cordata on uranium-contaminated soil,offering a promising approach for enhancing phytoremediation.
