XRD measurements of heavy metal contaminants in contact with zero-valent iron laboratory batch experiment

Included are the XRD raw data files and mineral interpretations conducted by Damian Gore. One gram of iron in contact with 250 mL of 1.5 mM copper or zinc solution was left covered from light and not stirred for 42, 84 or 321 days.

Samples were filtered, air dried and ground before XRD analysis using a Bruker AXS D8 Advance. Notable settings consisted of a 40 kV, 30 mA X-Ray source (Lambda = 1.5418 Angstroms), with a 0.6 degrees slit, a scan range of 10 to 90 degrees 2 Th. with a step size of 0.030 and a time step of 0.5 s. In an attempt to distinguish between different spinals the scan range was increased to 6 to 140 for the collection of selected diffractograms.
