摘要
研究了以水溶性5-Br-PAN-S为指示剂,配位滴定耐火材料原料中的三氧化二铝的方法。试验结果表明,5-Br-PAN-S是一种EDTA配位滴定法的良好指示剂。
A derivative of PAN,namely 5-Br-PAN-S,is used as a metallochromic indicator in chelatometric titration of aluminium in refractories. The advantages of this new indicator are its sensitivity, water-solubility and stability.
