Flame Photometric Determination of Copper in Mineral Mixes. Ion Exchange Technique for Sample Preparation

Sample Preparation for Flame Photometry Ion Exchange Separation of Copper, Maganese, and Iron

“…Sensitivity of the iron determination probably could be enhanced by using an organic solvent (1, S, 5). DISCUSSION Schrenk, Graber, and Johnson (6) did not effect complete separation of Fe(III) from Cu(II) in their study of the ion exchange separation of Cu(II) from other ions. Manganese also was not retained on the column as a complex anion under their conditions.…”

“…Peter E. Wei Esso Research and Engineering Co. Linden, N. J. Sample Preparation for Flame Photometry Ion Exchange Separation of Copper, Manganese, and Iron Sir: Schrenk, Graber, and Johnson (6) recently reported on an anion exchange procedure for the separation of copper prior to flame analysis for the element. The procedure was based on the work of Kraus and Moore (4) on anion exchange separations of the transition elements, manganese to zinc.…”

Emission Flame Photometry

“…Fabrikova (35) describes a procedure for the determination of rubidium in silicates, and Fabrikova (36) and Lebedev (62) have analyzed minerals for cesium. Schrenk, Graber, and Johnson (111) employed an ion exchange separation for the flame photometric determination of copper in mineral mixes. Ford (39) was able to determine magnesium, manganese, sodium, and potassium in a single solution of a cement sample with good accuracy and precision in much less time than by standard procedures.…”
