Nettet24. apr. 2024 · A common technique to quantitatively estimate P speciation in soil samples is to apply linear combination fitting (LCF) to normalized P K-edge X-ray absorption near-edge structure (XANES) spectra. Nettet14 I. LINEAR COMBINATION FITTING (LCF) OF MNL 3 EDGE 15 The linear combination tting (LCF) procedure was done at MnL 3 edge to calculate the Mn-ion average valency and the Mn+2, Mn+3 and Mn+4 contribution in the Al 16 2O 3 coated and uncoated LMO electrodes. For the LCF procedure, the reference spectra (in Fig.S1- left …
