摘要:
Chelating agent contributes to the remediation of heavy metal contaminations, but it remains unclear how they affect the transformation of radioactive pollutants and microbial traits in phytoremediation. We comprehensively investigated on the uranium (U) speciation and microbial communities in the rhizosphere of Macleaya cordata , Paspalum scrobiculatum and Bamboo willow , and analyzed the accumulation of U in the three plants after the addition of chelating agents including 0.1 mmol kg −1 siderophore (DFO) and 2.0 mmol kg −1 oxalic acid (OA)...
