Fractionation by Complexing Agents

Although even the agents which are very slightly soluble show an optimal

It is the writer s opinion that the phenomena met with in the foregoing description can readily be accounted for, without resort to one or other of the more speculative concepts regarding the structure of the adsorption complexes. 

The potentiometric, iodine titration clearly shows the adsorptive powers of both starch fractions, namely, their relative affinities for iodine in a quantitative way. As is well known, the iodine affinity of amylose depends on its chain length, the shorter chains having the lower affinity. Evidently,
