摘要：

New indirect X-ray methods have been developed for the determination of traces of lithium, beryllium and phosphorus. In the lithium method which is suitable for 1-100 μg Li, 50 μg of ammonium ion, 100 μg of sodium and 1 mg of K, Rb or Cs can be tolerated; larger amounts require an extraction process. Other interfering ions may require a cation-exchange separation. For the determination of beryllium (0-40μg),there are very few interferences when beryllium is precipitated as phosphate in the presence of EDTA.For the determination of phosphorous is used as precipatant. © 1969.
