Potentiometric measuring systems for the determination of organic electrolyte in an aqueous solution containing potassium chloride and sodium

摘要

The invention relates to potentiometric analysis, and chemometric techniques.; Technical result: the expansion of the analysis of objects, increasing the sensitivity and stability of the analysis operation simplification, an increase in determination accuracy.; The invention can be used for quantitative monitoring of organic electrolytes (amino acids, vitamins, drugs) in the raw materials, products and waste food and pharmaceutical industries, waste structural units of the health care system and for the continuous quantitative control of organic electrolytes at all stages of their preparation, separation and cleaning.; The inventive potentiometric measuring system is organized on the basis perekrestnochuvstvitelnogo sensor whose response is a potential difference at the interface sulfokationitovy perfluorinated polymer (SRP) / sample solution, a set of ion-selective electrodes, silver chloride reference electrode, a multi-channel voltmeter, the control block. 5 FIG.
