Quantitative Zinc Speciation in Soils
Description
A team of French researchers working at the Advanced Light Source (ALS) and the European Synchrotron Radiation Facility (ESRF) in Grenoble has shown how to use complementary x-ray techniques to identify zinc-containing compounds in contaminated French and Belgian soils located near smelters. In particular, they combined spatially resolved (at the µm scale) x-ray fluorescence (µ-XRF) and extended x-ray absorption fine structure (µ-EXAFS) at the ALS and polarized EXAFS at the ESRF to make the key identification of important zinc constituents and their structural forms (i.e., their speciation).
