“…Therefore, because of its increasing use and also due to toxicity of palladium(II) compounds to mammals, fish and higher plants (Lee, 1983), the determination of this pollutant in environmental matrices is of considerable importance for human exposure assessment and for the investigation of correlations with health effects. Several analytical methods have been reported based on atomic absorption spectrometry (Cetin et al, 2013;Tillery and Johnson, 1975;Tokalioglu et al, 2004;Chwastowska et al, 2004;Rojas et al, 2006;Liang et al, 2009), inductively coupled plasma spectrometry (Moldovan et al, 2003), differential pulse polarography (Dias and Nozaki, 1998), high performance liquid chromatography (Dong et al, 2006), derivative spectrophotometry (Vojkovic and Druskovic, 2003;Kumar et al, 2009), kinetic spectrophotometry (Niazi et al, 2008), extractive spectrophotometry (Kanetake and Otomo, 1988;Reddy et al, 2008;Safavi et al, 1997;Davis, 1969) and spectrophotometry (Mori et al, 1999;Marczenki and Kus, 1985;Otomo, 1963;Horiuchi and Nishida, 1967;Mizuno and Miyatani, 1976;Marczenki, 1986).…”
