Microanalysis of organolanthanum compounds

Simultaneous elemental microanalysis of organolanthanum compounds for C, H and La by the straight empty tube method of Korshun-Klimova is described. Additionally, complexometric, potentiometric, and spectrophotometric methods have been developed for the determination of the lanthanum content after oxygen flask combustion or wet digestion on micro, semimicro and submicro scales, respectively. The overall standard deviation for each of the 3 elements in the 5 compounds analyzed is 0.11%, whereas, the s value for La by the 3 methods is 0.11, 0.12 and 0.12%, respectively
