C 1s K-edge near edge X-ray absorption fine structure (NEXAFS) spectroscopy for characterizing functional group chemistry of black carbon
چکیده انگلیسی
► The complexity of black carbon within environmental matrices presents a challenge to distinguish it from other carbon. ► NEXAFS spectroscopy was used to characterize the C chemistry of a broad range of black carbon reference materials. ► Shale and melanoidin were distinguishable from the reference materials, but coals shared functional group distributions. ► Resonance in aromatic C regions obtained with NEXAFS and DPMAS correlated well (r2 = 0.633). ► Values for NEXAFS were around 30-40% lower than for NMR.
