Correlation of X-ray fluorescence (XRF) spectrometry and inductively coupled plasma atomic emission spectroscopy (ICP-AES) for elemental determination in compost
With the advent of field portable x-ray fluorescence (XRF) technology, elemental determinations are now possible in the field. The application of this technology has been studied for use in metallurgy, soil science, etc. However, little work has been done to ascertain the potential uses of XRF in compost analysis. To that end, seventy five compost samples were collected and analyzed with inductively coupled plasma atomic emission spectroscopy (ICP-AES) and field-portable XRF technology. Results showed strong correlation between testing methodologies for some elements (Cu, As, Zn) but poor correlation for others (Ca, K, Mo). While XRF does not provide the detection limits afforded by ICP, it does have utility as a field screening tool to quickly check if compost samples are below government-mandated threshold limits.
