The importance of beryllium and beryllium oxide to the atomic energy program has necessitated the development of accurate methods of chemical analysis for the determination of metallic innpurities. A method is presented for separating iron by extraction with tri-noctylphosphine oxide followed by determination with 1: 10-phenanthroline. The method is accurate to plus or minus 3% or plus or minus 3 micrograms of iron, whichever is greater. The accuracy and sensitivity could be increased by appropriate choice of sample weight, volume of extract, and/or cell length. Of the 68 elements investigated, 61 do not interfere in 10-mg amounts. No interference is caused by 5 mg of silicon, 1 mg of antimony, gallium, molybdenum, or tungsten, or 0.1 mg of tellurium or uranium. Only gallium, tellurium, and silicon interfere without producing a warning turbidity in the colored solution. (auth)
