Abstract : Improved methods are proposed for the determination of barium, strontium, calcium, and iron in barium peroxide. The barium is determined as barium chromate, using the technique of homogeneous precipitation. The filtrate from the barium chromate is treated with ammonium oxalate and ethyl alcohol to precipitate the strontium and calcium oxalates, which are then converted to the nitrates. The strontium and calcium nitrates are separated by the use of acetone and the strontium and calcium are finally precipitated as the sulfates. Iron is determined spectrophotometrically with orthophenanthroline. (Author)
