Comparison of Elemental Analysis Techniques for Fly Ash from Municipal Solid Waste Incineration using X-rays and Electron Beams

Abstract

With the rapid expansion of the waste incineration business both in Europe and globally, there is a growing need for the elemental analysis for fly ash from municipal solid waste incineration. In this work, samples of washed and unwashed ash from municipal solid waste incineration in Sundsvall are evaluated. Qualitative analysis and semi-quantitative analysis are used to compare two elemental analysis methods, scanning electron microscope with energy dispersive spectroscopy (SEM-EDS) and X-ray fluorescence (XRF) measurement. Both methods are used to retrieve the difference in elemental composition between washed and unwashed fly ash. SEM-EDS accurately detects light elements from well-prepared samples in a vacuum environment, while, for online measurements, XRF is a potential method that analyses hazardous metal content in the fly ash.

Characterization, risk assessment, and potential utilization of fly ash from PLTSa Merah Putih at Bantargebang, Bekasi, Indonesia

“…The results match those of Tan et al [14], An et al [12], Sobala et al [13], and Ibrahim et al [15]. with literature data on MSWI fly ash by Reddy et al [16], An et al [12], Al-Ghouti et al [17], and Cao et al [18].…”

“…These results demonstrated that MSW incineration fly ash was categorized as a very active high-calcium fly ash [13]. The results match those of Tan et al [14], An et al [12], Sobala et al [13], and Ibrahim et al [15]. with literature data on MSWI fly ash by Reddy et al [16], An et al [12], Al-Ghouti et al [17], and Cao et al [18].…”

“…EDS analysis confirmed the presence of Ca, Ti, Si, and Al as major components of MSWI fly ash. Many peaks not observed in the EDS spectra are likely due to dissociation from deionized water[12]. This is consistent 1201 (2023) 012048…”

“…XRF analysis was chosen because it is fast and fully suitable for simultaneous quantitative determination, also it is cheaper than Neutron Activation Analysis (NAA) and faster than inductively coupled plasma atomic emission spectroscopy (ICP-AES) [12]. Table 1 demonstrates the results of elemental composition for the collected MSWI fly ash samples using XRF analysis.…”

Optimum phosphate ion removal from aqueous solutions using roller kiln industrial solid waste

“…The surface charge of the RK industrial solid waste was detected using dynamic light scattering instrument (ZetaSizer Nano Series (HT), Nano ZS, Malvern Instruments, UK) 26 , 27 . X-ray fluorescence (XRF) analysis was conducted to examine each oxide quantity contained in the RK solid waste 28 , 29 utilizing American Society for Testing and Materials (ASTM) recommendations (C114-18). The particle size distribution (PSD) was determined by employing a set of standard screens with standard openings utilizing the standard ASTM D 422/2007 for the method and ASTM E 11/2009 for the sieves.…”
