非晶态金属是一种新型金属材料,其中含有7～10%磷、1～2%硼。高硼一般采用强碱分离容量法测定,但是用于含高磷试样时,结果偏高。偏高量是磷和硼的合量。为了准确地测定硼,必须将磷和硼进行分离。本文阐述了这方面进行的工作。结果证明,用氯化钡-强碱分离磷和硼能够获得满意结果。试验部份一主要试剂混合指示剂:0.05克甲基红、0.1克溴甲酚绿、0.
Amorphous metal is a new type of metal material containing 7 to 10% phosphorus and 1 to 2% boron. Boron is generally used to determine the strong base separation capacity, but for high phosphorus containing samples, the result is high. High amount is the amount of phosphorus and boron. In order to accurately measure boron, phosphorus and boron must be separated. This article describes the work done in this area. The results demonstrate that satisfactory results can be obtained by separating phosphorus and boron with barium chloride-alkali. Experimental part of a major reagent mixed indicator: 0.05 g methyl red, 0.1 g bromocresol green,
