Micro X-ray fluorescence imaging and micro X-ray absorption spectroscopy of cadmium hyper-accumulating plant, Arabidopsis halleri ssp. gemmifera, using high-energy synchrotron radiation†
Abstract
Monochromatic high-energy X-rays (37 keV) focused into a microbeam (3.8 × 1.3 μm2) with a Kirkpatrick-Baez mirror allows us for the first time to reveal the striking sub-cellular distribution and the chemical form of cadmium in the cadmium hyperaccumulating plant, Arabidopsis halleri ssp. gemmifera, by detecting the Cd Kα line. Micro X-ray fluorescence analysis (μ-XRF) and micro
