Extraction voltammetric determination of silicon

A Survey of Applications of Polyoxometalates

“…The ability of Mo and W to form POMs with almost all elements of the periodic table, many of which exhibit distinct spectroscopic features, offers the opportunity to the analytical chemist to develop methodology for the determination of such heteroelements as well as for discreet compounds. And these activities do not seem to diminish with the progress of time. − …”
