Dissolved Organic Matter, Cadmium, Copper and Zinc in Pig Slurry- and Soil Solution- Size Exclusion Chromatography Fractions

摘要

Sephadex size exclusion chromatography was used to prepare molecular size fractions from liquid pig slurry, before and after aerobic interaction with a loamy-sand soil. In the liquid fractions organic matter was characterized and some components were identified.
