Sd. Jadhav et Zr. Turel, DETERMINATION OF CHROMIUM IN AQUATIC ENVIRONMENT BY SUBSTOICHIOMETRICTHERMAL-NEUTRON ACTIVATION-ANALYSIS, Journal of radioanalytical and nuclear chemistry, 177(1), 1994, pp. 185-191
Chromium has been determined in environmental samples. The method desc
ribed here involves the irradiation of environmental samples and a mug
quantity of standard with thermal neutrons at the self-serve position
in the CIRUS reactor, followed by dissolution of the sample and stand
ard in the presence of a milligram amount of carrier. Both the sample
and the standard are subjected to substoichiometric extraction under c
ontrolled experimental conditions with alizarin into cyclohexane. An a
liquot of the organic phase was counted on a gamma-ray spectrometer. T
he concentration of Cr in water samples from Bombay and Karad City, an
d the accuracy, precision and sensitivity of the method are discussed.
