摘要
研究在室温下,1.0～3.2mol·L^(-1)盐酸介质中,用溴酸钾标准溶液氧化Sb(Ⅲ)至Sb(Ⅴ)以电位滴定确定终点的新方法,应用于巴氏轴承合金中锑含量的测定,方法简便、快速,结果准确可靠。
A method for potentiometric titration of Sb3+ with BrO3- in 1.0-3. 2mol ?L-1 HC1 at ambient temperature is reported in this paper. The method is simple and rapid without the need of expensive equipment. It has been used for the determination of antimony in white metal bearing alloys with satisfactory results.
