TL;DR: In this article, an iterative target transformation factor analysis (ITTFA) was applied to the determination of mixtures of pyrazines at trace level (2.0 −9.6 moll −1 ) by using differential pulse polarography and a static mercury drop electrode (SMDE).

TL;DR: In this article, a nonlinear model between the composition of the mixed metal ions and the measured pH responses in titration procedures was established, and was then used to predict unknown mixed metals.
