Organic matter extracted by electro-ultrafiltration (EUF) from an Alfisol, was characterized by high performance size exclusion liquid chromatography (HPSEC), elemental analysis, functional group determinations, E4/E6 ratio, and by UV, fluorescence and FT-IR spectroscopy. In most cases HPSEC showed the presence of two fractions. Chemical and spectroscopic data of organic matter extracted by EUF often overlapped very well with those of fulvic acid chemically extracted.

Abstract

Organic matter extracted by electro-ultrafiltration (EUF) from an Alfisol, was characterized by high performance size exclusion liquid chromatography (HPSEC), elemental analysis, functional group determinations, E4/E6 ratio, and by UV, fluorescence and FT-IR spectroscopy. In most cases HPSEC showed the presence of two fractions. Chemical and spectroscopic data of organic matter extracted by EUF often overlapped very well with those of fulvic acid chemically extracted.
