Abstract
Selenium reacts with ascorbic acid to give a light orange colour having maximum absorbance at 375 mm. The colour reaction has 1 Ng/m1 as the visual limit of identification and provides the basis for a new spectrophotometric method for the microdetermination of selenium from pure solution and biological materials which are of vital importance. The quantitative assessment of the tolerable amounts of different ions which do not interfere with determination has been reported.
