Ionometric Determination of Zn and Cd in Alloys

摘要

An easy to use and rapid procedure of ionometric determination of Zn and Cd in some alloys is presented. The method is based on the different capacity of complex formation of metal cations. Ion-selective electrodes with tetradecylammonium chloride and iodide were used as indicator electrodes. To separate Zn and Cd and to increase the selectivity of determination we used a sorption column with strong acid cationite KU-2. The procedure thus proposed provides 4-6 determination per hour.
