Summary
Experimental evidence is advanced which contradicts the view that the intercepts on the ordinate of plots of amount of cation absorbedvs time may be interpreted as representing the amount of ion initially bound to the sites involved in its active absorption and may be used to calculate the concentration of these sites.
