Abstract

Determining the chemical properties of waste is crucial to
ensure the most effective utilization of waste. The standard laboratory
measurements can produce accurate results, but analysis is labor- and
time-consuming. The variety of elements that field portable X-ray fluorescence
spectrometry (FPXRF) can detect from selected waste materials was studied,
including how the results compared with those of inductively coupled plasma
mass spectrometry (ICP-MS) measurements. The selected materials were fine
fraction reject from solid recovered fuel production, fly ash, biowaste, and
compost. Based on the results, FPXRF is reported to be best suited for waste
samples, such as ash and compost, because of their physical properties, as
follows: not too moist, quite small particle size, and not too heterogeneous.
The results obtained from FPXRF showed the lowest relative standard deviation
for ash material. The analysis of the limits of agreement between FPXRF and
ICP-MS showed that FPXRF was mainly suitable for qualitative assessment.
Furthermore, regression analysis showed a linear correlation between FPXRF and
ICP-MS results for calcium and zinc in the selected materials. Keeping the
limitations in mind, FPXRF could be used for qualitative analysis in waste
treatment processes, such as first quality control of waste materials.
