Open publisher page 0 citations

Abstract

The colour reactions of barium (Ⅱ) and strontium (Ⅱ) with dibromomethyl carboxyazo were studied comparatively. In the medium of H3 PO4, the colour reaction of barium (Ⅱ) is highly selectivity and tolerates the existence of 6 - fold of strontium(Ⅱ). And in the buffer medium of H3BO3 - Na2B4O7,the absorbances of colour coordination compounds for barium(Ⅱ) and strontium(Ⅱ) have an additivity over a certain range of concentrtion.On these grounds, a new method of the successive determination for barium and strontium had been developed.
