Reversible sorption and irreversible binding of naphthalene and alpha-naphthol to soil: elucidation of processes

Article Abstract:

The presence/absence of O2 and the presence/absence of biological activity were varied during the sorption period for an operational definition of biological coupling conditions to determine the extent of biologically mediated oxidative coupling's contribution to the irreversible binding of alpha-naphthol. This was performed as part of the evaluation of the sorption and irreversible binding of naphthalene and alpha-naphthol to two sandy soils. The concept of superposition was applied to alpha-naphthol results to establish the contribution of individual irreversible binding processes.

Fractionation of natural organic matter by size exclusion chromatography - properties and stability of fractions

Article Abstract:

In this study, an aquatic natural organic matter sample was concentrated by membrane filtration and fractionated to study stability over time. The article is broken down into an introduction, a discussion of materials and methods used for the experiment, and a discussion of the results of the experiment.

Dissolved organic matter apparent molecular weight distribution and number-average apparent molecular weight by batch ultrafiltration

Article Abstract:

Researchers from the Virginia Polytechnic Institute and State University determined the molecular weight distribution of dissolved organic matter in sample natural water and used a two-parameter permeation model to collect batch ultrafiltration data.
