Application of substoichiometric radioisotopic dilution to extraction of trace-level cadmium
The International Journal of Applied Radiation and Isotopes
|April 1, 1983
Abstract:
A substoichiometric isotopic dilution method was coupled to the standard addition technique for the determination of trace-level cadmium. 109Cd carrier-free as a radiotracer and extraction with dithizone in chloroform were used. A preconcentration procedure, which also cuts down the main interferences, for tap and natural waters was suggested. The sensitivity and accuracy of the method are discussed.
