The levels of trace elements and polycyclic aromatic hydrocarbons (PAHs) in fly ash generated by coal combustion have received considerable attention in recent years, due to their potential environmental impact. Sixteen high priority PAHs and 14 trace elements in coal fly ash were measured. The particle sizes of fly ash showed a bimodal distribution, and most ash particles were within a range of 20-25 µm in diameter. The fly ash exhibited high contents of CaO and SO 3 , which was influenced by the desulfidation treatment of limestone. The Be, Cu, Ni, V, Se, Mo and Cd contents increased significantly with decreasing particle sizes of fly ash, while those of Zn and Pb showed no obvious trends. PAHs with three-and four-rings were the dominate species in all the fly ash. The amount low molecular weight PAHs with two-, three-and four-rings was inversely correlated with the particle sizes of the fly ash.

“…For example, Na, Ca, Mg, Al, Fe, and Si in lignite were analyzed quantitatively in an early research by Wallis et al [4]. In addition, the inorganic elements in coal combustion product such as fly ash and bottom ash were also studied [5][6][7]. Quantitative compositional characterization of inorganic elements has also been performed by LIBS under different operating conditions in thermal power plants [8].…”

Quantitative carbon measurement in anthracite using laser-induced breakdown spectroscopy with binder

Quantitative carbon measurement in anthracites remains difficult with laser-induced breakdown spectroscopy (LIBS) due to its relatively high measurement uncertainty. To improve the measurement repeatability, binders to bind the anthracite powder together were utilized for LIBS measurement. Results showed that the optimized binder Na(2)SiO(3)·9H(2)O, with Si from the binder as the internal calibration element, can yield the overall best measurement precision and accuracy. Using 15 anthracites for calibration and 7 anthracites for validation and with optimized percentage of Na(2)SiO(3)·9H(2)O as binder, the average value of the measurement's relative standard deviation (RSD), R(2), and root mean square error of prediction (RMSEP) were 12.1%, 0.76, and 6.25%, respectively, proving the applicability of binder for carbon measurement in anthracites.
