Abstract

The distribution behavior of 8-quinolinols (HQ) in organic and acidic aqueous solutions (or alkaline solutions) was electrochemically examined by current scan polarography and chronopotentiometry. It follows from the results that the half wave potential of the observed polarographic waves, corresponding to the Faradaic transfer of quinolinolium ions (or oxinate ions) formed in the aqueous solution after distribution of quinolinols is dependent on the dissociation constant of H(2)Q(+) (or HQ) and the pH of the aqueous solution, but independent of the distribution constant of 8-quinolinols.
