The determination of lanthanum by measuring its flame emission at several wave lengths has been evaluated by means of two recording spectrophotometers equipped with special photomultiplier detecting devices. In addition. a comparison of the effect of an aqueous and alcoholic medium was carried out. In general, the interference from foreign ions is least at the higher wave length of 743 m mu . In most cases, especially with transition elements, the interference is lessennd when 1: 1 water--methanol solution ls used. The exceptions to this rule are titanium, thorium, and zirconium which cause less interference in an aqueous solution. The method used in conjunction with a standand addition technique, has been applied to the determination of lanthanum in solutions of thorium oxide, uranium, glass, and didymium oxide mixtures.
