The decomposition of two lanthanoid minerals, viz fluorocarbonate bastnasite and phosphate monazite, is described. Iron present in the solution obtained is removed on anion exchanger. Atomic absorption spectrophotometry was applied to the determination of the minor elements present in the mineral, viz. copper, lead, calcium and magnesium. The measurement conditions for the determination of these elements in microquantities were established by using model solutions, and the accuracy and precision of determination were evaluated.

Abstract A procedure is described for the automated simultaneous determination of serum calcium and phosphate. Calcium is assayed by atomic absorption spectrophotometry. Phosphate is determined by the molybdenum blue reaction in an improved flow system with a more sensitive reducing agent.

Abstract The atomic absorption method studied last year was re-examined and extended to include calcium and sodium. The procedures were submitted to 16 collaborators for determination of Ca, Cu, Fe, Mg, Mn, Na, and Zn. Results for Ca and Na were discouraging; further study is recommended.
