Dissolved yellow organics: quantitative and qualitative aspects of extraction by four common techniques
Abstract
The dissolved yellow organic matter is removed from aliquots of the same freshwater sample by four common techniques: lyophilization, ion-exchange, ultrafiltration and organic solvent. Quantitative and qualitative aspects of the recovery, including fractionation by gel filtration and total nitrogen determinations, are presented.
