Water-soluble organic carbon (WSOC) was extracted from the surface horizon (0–15 cm) of a South Carolina floodplain soil (Pickney series-sandy, silicious, thermic Cumulic Humaquepts) using either 1.2-µm Whatman glass fiber type C (GF) or polycarbonate (PC) (<0.4 µm) filters. The trend in functional group C distribution for both WSOC fractions was O-alkyl > aliphatic > aromatic > carboxylic acid > carbonyl structures. Overall, the 13C NMR spectra showed similar functional group C distributions for fractions obtained with both filters.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
