Preparation, properties and analytical application of thorium n-phenyl-o-nitrobenzohydroxamate.
A new complex of thorium(IV) with N-phenyl-o-nitrobenzohydroxamic acid (PNHA) has been prepared by reacting an aqueous solution of thorium with an alcoholic solution of PNHA at 60 degrees C and adjusting the pH to 4-4.5. The infrared spectra and thermal analysis of the complex are discussed. The use of PNHA for gravimetric determination of thorium is described.
