Activated carbon adsorption of humic substances

Open access

Abstract

The activated carbon adsorption isotherms for a wide range of humic substance molecular size (MS) fractions display an inverse dependence on MS, when expressed on an adsorbent mass basis. However, normalizing the amount adsorbed on the basis of available adsorbent surface area accounts for the size exclusion behavior displayed by the MS fractions, resulting in convergence of their isotherms. The available surface area was calculated by relating the hydrodynamic size of the macromolecules to the adsorbent pore size. The effects of adsorbent charge and solution ionic strength conform to adsorption electrostatic principles when the isotherms are expressed on an available surface area basis. Adsorbents with progressively more positively charged surfaces adsorb more of the negatively charged humic substances. Increasing solution ionic strength suppresses adsorption by a positively charged adsorbent and enhances the adsorption by a negatively charged adsorbent. The characteristic, two-segment shape of the MS fraction isotherms is interpreted based upon changes in adsorbed macromolecule orientation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
