Macro- and microelement characterisation of Juncus inflexus biomass treated with rare earth elements

This data set presents the elemental analysis of Juncus inflexus biomass divided into underground parts (roots) and above-ground parts (stems/flower). Juncus inflexus was treated with synthetic wastewater enriched with rare earth elements (REE). Three distinct treatments were prepared with a wide range of REE concentrations:
Treatment 1: Y+Sc: control, 1 mg L-1, 5 mg L-1, 10 mg L-1, and 20 mg L-1
Treatment 2: Gd: control, 1 mg L-1, 5 mg L-1, 10 mg L-1, and 20 mg L-1
Treatment 3: La+Ce: control, 1 mg L-1, 5 mg L-1, 10 mg L-1, and 20 mg L-1
Juncus inflexus plants were subjected to N, P, and REE solutions for 14 days.
The elemental analysis was performed using a non-destructive XRF method (Bruker Titan S1, USA). The recoveries were determined using the Bruker Plant Calibration for Portable X-Ray Fluorescence (pXRF) and approved reference materials (strawberry leaves, LGC 7162).
