摘要
研究了铜锆中间合金中铜、锆的测定方法。试样经高氯酸、硝酸分解后,采用电解法测定铜:分离铜后的电解液,经盐酸处理后以二甲酚橙为指示剂,用EDTA标准溶液滴定测定锆。该方法简便,具有良好的精密度和准确度,相对标准偏差分别为铜0.19％。锆0.15％。
The copper and zirconium contents in cupro-zrrconium intermediate alloy have been determined.After the sample has been decomposed by perchloric acid and nitric acid,the copper content can be determined by electrolysis.The rest electrolytic solution will be treated by chlorhydric acid and titrated by EDTA standard solution to determine zirconium content in the condition that xylenol orange be used as tracer agent.A good accuracy can be attained by using this simple method.The standard errors are respectively 0.19% for copper and 0.15% for zirconium.
