“…To obtain a suitable count rate and characteristic peak resolution, the XRF spectra of soil samples were collected using the spectrometer at 45 kV tube voltage, 26 μA current, and 90 s measurement time. 34 Due to the inherent heterogeneity and complexity of soil samples, spectra collected from the same samples will have varying degrees of fluctuating behaviour. To reduce the error caused by such fluctuation, we scanned each sample three times and took the average value as the final XRF spectral data for analysis.…”
Measuring accurate concentration levels of potentially toxic elements in agricultural soils is necessary to prevent hazards to human health. X-ray fluorescence spectroscopy (XRF) allows rapid, non-destructive detection of potentially toxic...

“…9 Moreover, XRF has the ability of real-time detection and can be used for in situ or ex situ measurements. Due to its promising applications, XRF technology has been widely utilized in soil analysis, 10 geological exploration 11 and quality monitoring. 12 However, the elemental composition of soils is extremely complex.…”
An accurate and effective analytical method to measure the concentration of heavy metal elements (HMEs) in soil is of great significance for combating soil pollution, repairing ecosystems, and guiding agricultural...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
