Citrate assisted phytoextraction of uranium by sunflowers: Study of fluxes in soils and plants and resulting intra-planta distribution of Fe and U

Popis výsledku v původním jazyce

This study aimed to determine how the citric acid assisted phytoextraction of uranium (U) by sunflowers impacted on the remobilisation of U in soil, its subsequent transfer to plants and its further distribution intra-planta. Consequences of the flux ofnutrient elements [iron (Fe) and zinc (Zn)] able to interfere with U during this process were also specifically addressed. A U-contaminated soil receiving different citric acid treatments in terms of dose delivered and frequency of delivery was studied.Dynamics of remobilisation in soil were assessed using DGT (Diffusive Gradient in Thin-film) measurements, and phytoextraction experiments were conducted in a Rhizoplan device. All treatments induced a remobilisation of U and Fe from the soil solid-phaseto the soil solution. Consequently, sunflower uptake of U was greatly enhanced, whereas the uptake of Fe was not affected. As for U, the Zn uptake increased due to the citric acid treatment.
