The identity and characteristics of aquatic soluble phosphorus (SUP) present in a small mid-western mesotropic lake were examined with 31-Phosphorus Fourier Transform Nuclear Magnetic Resonance Spectroscopy $\rm (\sp{31}P$ FT-NMR) and High Performance Liquid Chromatography (HPLC). Samples were concentrated and fractionated according to molecular size using a series of ultrafiltration (UF) and reverse osmosis (RO) membranes. The UF membrane pore sizes were 30,000 Da and 1,000 Da while the RO membrane had a 95% NaCl rejection rating. The SUP was analyzed as a function of apparent molecular size and season. In the 30,000 Da retentate, monoester phosphates, diester phosphates, and phophonates were detected. In the 1,000 Da retentate, monoester ...
