Abstract : The book discusses the theoretical and practical aspects of the use of the reagent arsenazo III and some of its analogs for the determination of thorium, uranium, zirconium, hafnium, scandium, cerium, lanthanum, rare earth elements, plutonium, neptunium, curium, protactinium, niobium, barium, strontium and sulfur. The first part of the book considers the mechanism of complexing and color reactions, the composition and structure of the complexes, the selectivity and other general properties of reagents of the arsenazo-thoron group. The second, practical part of the book gives complete descriptions of methods for determining the series of rare and actinide elements with arsenazo III and its analogs in various substances, and indicates the selectivity, sensitivity, photometry conditions and other data. Most of the techniques have been worked out for the analysis of specific materials, but with some modifications (decomposition of the material, choice of the most efficient methods of separating impurities for a given case, etc.), they can be used as guidelines for determining elements in other materials as well.
