✦ Synopsis

The dc polarographic behavior of metronidazole is studied in McIlvaine buffers. The reduction is irreversible and exhibits two waves; the first is suitable for analytical purposes. The limiting current shows a linear dependence with the drug concentration in the range 0.02-1 mM. A new polarographic method is examined for determination of metionidazole in commercial tablets and human urine.

A simple design of a polarographic flow-through cell is proposed in which a conventional dropping mercury electrode (DME) is used as working electrode, and a mercury pool and a platinum wire are used as the reference and counter electrodes, respectively. The mercury droplets falling from the DME coa

Different approaches for the colorimetric determination of acetaminophen, based on its coupling with diazotized o-nitroaniline, are described. Copper(II) chelation with the coupled compound makes the method highly selective. Sensitivity is increased when the acetaminophen assay is carried out indire
