Epub 2011 Apr 20.Two analytical methods, which prove the utility of a potentiometric flow injection technique for determining various redox species, based on the use of some redox potential buffers, are reviewed. The first is a potentiometric flow injection method in which a redox couple such as Fe(III)-Fe(II), Fe(CN)(6) (3-)-Fe(CN)(CN)(6) (4-), and bromide-bromine and a redox electrode or a combined platinum-bromide ion selective electrode are used.
