A NEW APPROACH TO DETERMINATION OF CATION EXCHANGE CAPACITY

The dielectric dispersion defined as the difference in the dielectric constant of a sample measured at 3 x 10 to the sixth power Hz and at 75 x 10 to sixth power Hz, was linearly related to CEC of the sample. One linear relationship between the dielectric and CEC was obtained for clay-silica flour mixtures where CEC was varied by changing the proportion of clay in the sample as well as by using clays with different CEC (kaolinite, illite, montmorillonite). A second linear relationship, with somewhat different slope, was obtained between the dilectric dispersion and the CEC of natural soil samples. /Author/
