[Potentiometric concentration determination of cyanide ions in waste water]

Electrodic systems, consist of gold or silver and metals of the IV, or V, subsidiary groups of the periodic system of elements are qualified for that, because they based strength of their electrodic steepness, selectivity, potentionel stability and sensibility by destination of cyanid ions in waste-water. We are going to introduce a fast-analysis-method for cyanid ions in waste-water of technical processes, which had been tested practically by the continuous control of limits, demanded by the legislator.
