| Abstract: | The use of high-voltage electroaccumulation in the determination of silver by stripping voltammetry at a mechanically renewed
graphite electrode with an area of 2.5 × 10−3 cm2 in 0.2% boric acid acidified with acetic acid at a voltage of 400 V and at an accumulation time of 5 min lowered the detection
limit for silver to 1 × 10−12 M. |
