Amylose-Iodine Complex. II. Effects of Inorganic Salts

Abstract
The relations between the light absorptions of the amylose-iodine complex and the concentrations of various added salts have been investigated. The iodide ion appears to be indispensable for the formation of the blue complex. The complex formation can be greatly aided by certain salts when the concentration of iodide is low. This salt effect suggests that the parallel-oriented aggregation of amyloseiodine helical complex is essential for the formation of the stable blue complex.
