| 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. |
