“…One of the most popular methods for the separation of the Cr(III)-Cr(VI) species is the extraction of Cr(VI) with a liquid anion exchange solution (Amberlite LA-2/MIBK; Camara et al, 2000). Ion chromatography is also used for the separation of Cr species successfully (Arar & Pfaff, 1991, Arar et al, 1992Giuriati et al, 2005) and is adopted by US-EPA in method 7199, which describes the determination of hexavalent chromium in drinking water, groundwater, and industrial wastewater effluents by ion chromatography (U. S. EPA, 1996b). Detection is mainly accomplished by spectrophotometry at 540 nm, utilizing the well-documented diphenylcarbazide method (Arar & Pfaff, 1991;Giuriati et al, 2005;Wei et al, 1982).…”

However, in order to achieve lower detection limits, ion chromatography has been coupled with atomic spectrometric detection systems, such as flame atomic absorption spectrometry (Posta et al, 1993) and inductively coupled plasma with atomic emission spectrometry (Byrdy et al, 1995), or mass spectrometry (Arar et al, 1992;Byrdy et al, 1995).…”

“…HPLC with a convenient detector meets most of the analytical requirements of simultaneous metal determination such as separation, identification, and quantification of different species down to trace levels. A significantly higher sensitivity is achieved by using derivative HPLC with spectrophotometric detection (Arar and Pfaff 1991;Pobozy et al 1996;Padarauskas and Schwedt 1995). Derivative HPLC is not only a sensitive but also a selective and rapid method for the separation and determination of metal ions.…”

“…The commonly used methods for chromium determination include the spectrophotometric [5][6][7], chromatographic [8,9], flow injection-fluorimetric [10][11][12], atomic absorption [13][14][15][16] and electrochemical methods such as voltammetry [17][18][19] and polarography [20][21][22].…”
