Description

This report include: (1) corrected data and new data on cesium sorption by bulk graphite (H-451) with a discussion of anomalies and a comparison of the data; (2) a review of the exponential (Freundlich) isotherm theory and a derivation of the modified-exponential isotherm; (3) a report on a study by the pseudo-isopiestic method of cesium by H-451 graphite powder (size range 44 to 74 ..mu..m) of the type used in the Knudsen cell mass spectrometer method; (4) a comparison of the results on particulate graphite (powder) obtained by the Knudsen cell method and also a comparison of cesium sorption results ... continued below
