摘要
利用ＫＣＩ－Ｃｕ（Ⅱ）－ＥＤＴＡ缓冲溶液电解质体系发生ＣｕＣｌ研究了载金炭中金的精密测定。讨论了提高试样中测定金准确度和精密度的途径。结果表明，当载金炭中金品位大约为４０００ｇ／ｔ时，金的回收率在９８％－１０１．２％之间，ＲＳＤ＝１．８５％（ｎ＝６）。
The precise coulometric titration of gold in carrying gold carbon was carried out with electrogenerated* chlorocuprous ion in KCl-Cu-EDTA buffer medium. Some ways of increasing the accuracy and precision for the*determination of gold were discussed in detail The results showed that the recovery is between 98.0%-101.2%,and the* relative standard is 1.85% (n=6) when gold content is about 4000g/t.*
