Abstract
Solid modified and unmodified titanic electronic electrodes with stable electrochemical and operational characteristics, selective with cations of cuprum, zinc, cadmium were created. Potentiometric measurements were done with help of anion – 4100 with error 0.001 B. For researching of ionic strength on the values of potential and steepness of electrode function were measured potentials of background solution of studied salts. Preparation of solution at cadmium’s, nitrate’s background allows to hold definition at constant forces (I = 1). Beside the experiment proved that potential of titrated electrode in the concrete does not depend on concentration of selected background technique of determination of copper’s, cadmium’s, zinc’s cations in formation waters was developed. Possibility of processing titanium electrodes as indicator for copper’s, zinc’s, cadmium’s definition in formation waters by potentiometric titration’s method was shown.
keywords Potentiometric, titanium, electrodes, copper, zinc, cadmium, formation waters.
