碘量法测定铜系1854年建立,距今已有一百多年的历史。由于其严臻的理论基础、快速及较高的准确度等特点,所以除个别合金采用络合滴定法外,目前国内外测定常量铜仍以碘量法为主。在五十年代初期,我省曾用硫代硫酸钠分离法,但很快就被氢氧化铵分离铜(Ⅱ)、铁(Ⅲ)的氨法所代替。文献[1]的作者对铜 Iodometric determination of copper was established in 1854, dating back more than a hundred years of history. Because of its theoretical basis of Yan Zhen, rapid and high accuracy and so on, so with the exception of some alloys using complexometric titration, the current domestic and international determination of copper is still based on the amount of iodine. In the early 1950s, our province had used sodium thiosulfate separation method, but was soon replaced by ammonium hydroxide copper (Ⅱ), iron (Ⅲ) ammonia method instead. The author of [1] on copper
