[en] The review of the works starting from the middle 50-ties on the use of new organic reagents of hydroxamic acid class in analytical chemistry is presented. The fact that N-arylsubstituted derivatives of hydroxamic acids form low-soluble chelates with ions of different elements at different acidity is of special value. It permits to determine many elements, as well as rare ones, in multicomponent systems. N-benzoyl-N-phenyl-hydroxylamine and its analogous are successfully used in different electrochemical methods of analysis: extraction polarography, potentiometry, ionometry. Using the given reagents in electrochemical methods Zr, Sc, Nb, Ce, Mo, V, Th, La, In, Y can be determined. The application of hydroxamic acids in non-electrochemical methods of analysis is considered
