Catalytic determination of ultra trace amounts of vanadium with detection by linear sweep voltammetry

RETRACTED: Spectrophotometric determination of V(V) in environmental, biological, pharmaceutical and alloy samples by novel oxidative coupling reactions

“…Therefore, the determination of vanadium in environmental and biological samples is highly desirable. In survey of literature reveals that several analytical techniques have been reported for the determination of vanadium such as high performance liquid chromatography [2,3], voltammetry [4], atomic absorption spectrometry [5,6], spectrofluorimetry [7], atomic emission spectrometry [8] and ion chromatography inductively coupled plasma-optical emission spectrometry [9]. These techniques have also some limitations in terms of high cost of instruments used in routine analysis and matrix effects.…”

“…The usual way to determine vanadium content in environmental samples is to use spectrometric methods such as atomic absorption spectrometry (Chakraborty and Das 1994), inductively coupled plasma-mass spectrometry (Noguchi 2008), inductively coupled plasma-atomic emission spectrometry (Danzaki 1992;Osamu Noguchi et al 2009;Hakim et al 2007), inductively coupled plasma-optical emission spectrometry (Wuilloud et al 2000), voltametry (Ensafia and Naderi 1997), high-performance liquid chromatography (Wang et al 1995), spectroflurimetry (Kawakubo et al 1995), ion chromatography inductively coupled plasma-optical emission spectrometry (Coetzee et al 2002), and ETAAS (Saavedra et al 2004). However, these techniques require highly expensive instruments for routine analysis, which every laboratory cannot afford.…”

“…Thus a sensitive method of determining vanadium is necessary for studying diseases involving lack of vanadium or its excess. The analytical methods most often used to determine of vanadium in environmental samples are atomic absorption spectrometry [3,4], spectrofluorimetry [5], atomic emission spectrometry [6], high performance liquid chromatography [7,8], ion chromatography inductively coupled plasma-optical emission spectrometry [9] and voltammetry [10]. Unfortunately few of them have poor sensitivity to determine vanadium at ultra-trace level in natural water samples.…”
