Measurement of a Cation Exchange Isotherm from Elution Curves Obtained in a Soil Column: Preliminary Results
Abstract
Abstract It is shown how successive column experiments allow the measurement of exchange capacity and a composition‐dependent selectivity factor for the calcium‐potassium exchange process on a natural soil. The method is based on a simple model which describes (i) the coupling between the steady flow and the exchange process, and (ii) the solubility of calcite which is taken into account by assuming that the resulting excess in calcium is already in the feed. Comparison with classical batch measurements shows that the column experiments give more reliable results. Nevertheless, the accuracy of the method is limited by the efficiency of the packing of the column.

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.
