The goal of this research is phytoremediation of uranium-contaminated soil. In the preliminary investigation, Macleaya cordata (Willd.) R. Br. was found to grow in abundance around uranium tailings. Afterward, the field tests to remove uranium from the contaminated soil by the M. cordata (Willd.) R. Br. were conducted. After 3 years of treatment, the contents of uranium in the shallow, middle, and deep layers decreased by 51.2%, 16.6%, and 90.3%, respectively, indicating the transfer of uranium from the tailings. The content of uranium in the r...
