【摘要】 本文提出在ＨＡｃ—ＮａＡｃ介质中Ｃｕ３＋与Ｉ－、ＳＣＮ－反应生成Ｉ２，然后加入过量的Ｎａ２Ｓ２Ｏ３还 原Ｉ２，最后用电生Ｉ２回滴定过量的Ｎａ２Ｓ２Ｏ２。实验表明，用这种方法测定铜可行的，检测量可达 １０－７数量级．更多还原

【Abstract】 It is put forth in this article that. in medium HAc-NaAc, let Cu 2+ react with I-, and SCN- to produce I2. then over-much Na2S2O3 was added to reduces I2, and lastly titration of the over-much Na2S2O2 with eletrogenerated I2 wa made again Experiments manifest that this method is feasible for determining copper, with the determination being in the order of magnitude of 10-7g.更多还原
