Radiochemistry Aims and scope

Abstract

Anodic dissolution of lanthanum metal in the presence of acetylacetone in ethanol, acetonitrile, and water was studied. Adducts of lanthanum tris-β-diketonates [La(EtOH)0.5(AA)3], [La(HAA)(AA)3], and La(AA)3(H2O)4, respectively, were isolated from these solutions. Electrochemical oxidation of lanthanum in the course of electrolysis is accompanied by its chemical dissolution. The compositions of the compounds obtained were confirmed by IR spectroscopy, mass spectrometry, thermal gravimetric analysis, isothermal heating, and elemental analysis for metal.
