CYANAMIDE IONS POTENTIOMETRIC DETERMINATI ON IN THE WASTE-WATERS

The cyanide ion war determined by indirect and direct potentiometry Fo r determinations, an electrochemical cell with silver:electrode: and c yanide electrode as indicator electrodes and a saturated calomel elect rode, were used A standard solution of sliver nitrate was used as titr ate For these methods the interferences of F-, Cl-, Br- I- and SCN- io ns were studied. Using there methods the-cyanide ion can be determined in a concentration range of 10(-2) -10(-6) mole/l.
