Abstract

Metoda pentru determinarea concentratiei totale de ioni liberi din solutii, caracterizata prin aceea ca se determina suma produselor concentratie-mobilitate, (vezi form. în desc.) a tuturor ionilor liberi din solutia test indiferent de natura lor, pebaza masurarii tensiunii electrice U a pilei de concentratie cu transport, alcatuita din solutia test în contact electrochimic prin doua joctiuni lichide cu doi electrozi, dintre care cel putin unul este un electrod suma cel de al doilea putînd fi tot un electrod suma (15 II) sau un electrod de referinta, tensiune electrica a carei valoare creste odata cu dilutia solutiei test, avand expresia generala (vezi form. în desc.) în care valorile distantei la origine si pantei B sînt constante independente de compozitia solutiei test pentru o alcatuire data a pilei de concentratie si pentru temperatura si presiunea de lucru alese, aceste valori determinîndu-se experimental prin trasarea dreptei de variatie (vezi form. în desc.) pentru solutii decompozitie si pH cunoscute, într-un domeniu astfel încît suma concentratiilor cationilor (anionilor) sa fie speciale.
