    Notes: Abstract A substoichiometric radiochemical method has been developed for the determination of selenium with potassium ethyl xanthate. The selenium ethyl xanthate complex formed was extracted into chloroform from borate buffer at pH 5. The effect of foreign ions on the extraction was studied. Microgram quantities of selenium could be conveniently determined with a fair degree of accuracy. The method has been successfully applied for the determination of selenium content in food stuffs such as “Jaggery” and “Wheat powder”.

    Notes: Abstract A radiochemical displacement method has been developed for the determination of nickel and cobalt based on the release of Zn-65 from labelled Zn(PAN)2 [1-(2-pyridylazo) 2-naphthol] complex in chloroform. The displacement behavior of Zn-65 by nickel and cobalt was studied in the pH range 5–7.5. The effect of various ions on the displacement was also examined. 2–20 μg of nickel and cobalt was determined by the aid of calibration plots.

    Notes: Abstract In the present investigation, a simple and selective radioanalytical method for the evaluation of selenium in microgram amounts by substoichiometric isotope dilution analysis has been developed. Potassium benzyl xanthate has been employed as the reagent. The colorless selenium-benzyl xanthate complex was extracted into chloroform. The influence of various ions during the extraction was also critically examined. The method developed has been successfully applied for the analysis of a few agricultural products for selenium.

    Notes: Abstract The comparative extractability of zinc with potassium salts of ethyl, propyl, butyl, pentyl, and benzyl xanthates from the pH range of 3.5–9.0 into chloroform has been studied, employing a sensitive and rapid substoichiometric radiochemical method. The extent of reproducibility was tested in each case. The effect of associated ions on the extraction was studied. The amount of zinc present in the standard solutions was determined employing each xanthate separately. The zinc content present in geological water samples in and around Tirupati was determined by the method developed and compared with the values obtained by Atomic Absorption Spectrophotometry.
