Fe(II)/Fe(III) and Cu(I)/Cu(II) are electrophoretically separated as chelates of 4-(2-pyridylazo)resorcinol (PAR), 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP), and 4-(3,5-dibromo-2-pyridylazo)-N-ethyl-N-(3-sulfopropyl)aniline (3,5-diBr-PAESA). Micellar media are suitable for the prese
## Abstract The coprecipitation method is widely used for the preconcentration of trace metal ions prior to their determination by flame atomic absorption spectrometry (FAAS). A simple and sensitive method based on coprecipitation of Fe(III) and Ni(II) ions with Cu(II)β4β(2βpyridylazo)βresorcinol w
