Conclusions
- 1.
The behavior of ultrasmall amounts of indium on stationary mercury electrodes with gold, silver, and platinum contacts was studied using the method of dispersion analysis.
- 2.
A substantial influence of the concentration of the element to be determined and of the contact metal upon the height of the anodic peak of indium was established.
- 3.
An electrode with a silver contact is more suitable for determining low concentrations of indium by the method of amalgam polarography with accumulation than are the other electrodes used.
- 4.
The linear nature of the dependence of the height of the peak of indium upon the time of accumulation in the determination of indium on an electrode with a silver contact was established.
