The NMR and spectral study on the structure of molecular size-fractionated lignite humic acid
In this study, high pure humic acid (HA) extracted from lignite was fractionated into four fractions according to their molecular weights by the ultrafiltration method. The structural characteristics of various HA fractions were investigated by UV–Vis,FTIR, and 3D fluorescence spectra and 13C/1H-NMR...
