Abstract

This study evaluated the capability of FP-XRF (Field-Portable X-ray Fluorescence) to swiftly generate information of elemental amounts in DGT (Diffusive Gradients in Thin-film gels) devices. Biologically available metal ions in environmental samples passively preconcentrate in the thin films of DGT devices, providing an ideal and uniform matrix for XRF nondestructive detection. Strong correlation coefficients (r > 0.992 for Mn, Cu, Zn, Pb and As) between the concentration data from ICP-MS and FP-XRF analysis were obtained for all elements during calibration. When Pb and As co-existed in the solution trials, As did not interfere with Pb detection when using Chelex-DGT. However, there was a significant enhancement of the Pb reading attributed to As when ferrihydrite binding gels were tested, consistent with Fe-oxyhydroxide surfaces absorbing large quantities of As. This study provides a new and simple diagnostic tool for on-site environmental monitoring of labile metals/metalloids.
