摘要：
Titrimetric microdetermination of samarium and neodymium has been described with sodium rhodizonate. Trivalent salts of samarium and neodymium form violet colored complexes in the ratio of 1:3. The complex is dissolved in dilute acid and the rhodizonic acid that is attached with the metal ion is estimated by titrating against a standard solution of ceric sulfate using N-phenyl anthranilic acid as indicator. Interference of cations has been observed. © 1968.
