International Series of Monographs in Analytical Chemistry, Volume 37: Microanalysis by the Ring-Oven Technique, Second Edition focuses on the ring-oven method. The book first offers information on the characteristics and uses of ring-oven, gas generator, pipette, glass holder, and other accessories. The text focuses on qualitative analysis, including the systematic schemes for the analysis of metal ions; separations and reactions for acid radicals; and reactions for metal ions. The selection discusses spot colorimetry with the ring-oven method. Concerns include determination of iron and other metals, amplification reactions, removal of interfering ions, and determination of anions. The radiochemical applications of ring-oven method, including determination of inactive substances, identification of radionucleides, and separation procedures, are explained. The text also discusses the combination of ring-oven method with electrography, thin-layer chromatography, and solvent extraction. The book is a valuable source of information for readers interested in the ring-oven method.
