Use of portable X-Ray fluorescence signal for characterization of soil physical parameters: A feasibility study

摘要

In aim of environmental assessment of urban areas or of restoration of ancient industrial sites, high-yield field methods for soil characterization such as portable XRF (X-ray fluorescence), have advantage of providing the main chemical composition within being rapid, cheap and non destructive (Peinado et al. 2010). Recent studies highlighted that portable XRF data can be considered as quantitative for some of analysed metal elements and semi-quantitative for others (Branchu et al. 2013). However, the portable XRF (PXRF) was shown to be sensitive to matrix variations (water content and texture, Zhu et al. 2011).
