Granular ZVI reacted with 17 mM TcO4− in 80 mM NaCl for one month. a HAADF STEM micrograph of Tc-containing lamella; b higher magnification HAADF image of the area outlined in white on the image (a); c bright field STEM image collected concurrently with (b); d−f EDS maps of the area shown in b and c indicate homogeneous distribution of Tc within oxidized ZVI. The mineral phases shown in this area could not be identified.
