Изучение возможности использования твердого композитного электрода для потенциометрического определения кадмия в растворах

Abstract

The article presents the results of a study the possibility of potentiometric titration of the solution containing Cd (II) by the solution of sodium diethylditheocarbamate (DDTC-Na) using carbon composite electrode(CCE). The conditions for potentiometric determination of Cd (II) (working concentration range, pH, supporting electrolyte, working concentration range, frequency ultrasound).The titration curves were processed by the linearization method. This method is based on the transformation of the titration curve into a line of multiphase regression, whose parameters determine the equivalence point with high accuracy.
