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