INFLUENCE OF THE NATURE OF METAL IONS ON THE EXTRACTION CONSTANTS OF THEIR DITHIOCARBAMATES

Abstract

ABSTRACT It is demonstrated that the electronegativity of metals extracted in the form of diethyldithiocarbamates affects the extraction constants in two ways, namely, through its influence on the chelate stability and the partition constants. The corresponding interrelations can be used to predict extraction constants from any of the following three characteristics: the Klopman electronegativity of the metal, the chelate partition constant, or the chelate stability constant.
