摘要
讨论了盖式漏斗碘量法测定含铜锡物料的分析,用铁粉置换分离后,加入混合指示剂,分析结果的精密度及加标回收均取得理想效果。本方法适用于10%~70%含锡量的含铜锡物料的分析。
This method is suitable for 10% - 70% tin content of copper-containing materials. In this paper, we discuss the analysis of copper-containing materials by cap-type funnel iodometrie method. After separation with iron powder, the mixed indicator is added, and the precision of the analysis resuh and the recovery of spikes are achieved.
