A radiochemical method has been developed for the determination of microgram amounts of cadmium based on the substoichiometric extraction of its 1: 2 complex with potassium ethyl xanthate into 1: 4 v/v mixture of pyridine and ethyl acetate from 2.5M sodium formate. 10-90μg of cadmium was determined with an average error of ±1.96%. The method developed was successfully applied to the determination of Cd contents in water samples.
