Abstract
It is demonstrated that the electronegativity of metals extracted in t he 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 charac teristics: the Klopman electronegativity of the metal, the chelate par tition constant, or the chelate stability constant.
