Preconcentration, speciation and determination of ultra trace amounts of mercury by modified octadecyl silica membrane disk/electron beam irradiation and cold vapor atomic absorption spectrometry

Spectrometric Determination of Copper in Edible Oil Based on the Extraction with N,N′-bis(5-methoxy-salicylidene)-2-hydroxy-1,3-propanediamine

“…Schiff bases derived from salicylaldehyde as polydentate ligands are known to form stable complexes with transition metal ions (Ashkenani et al, 2009;Bağdat Yaşar, 2010, 2012a). There have been some researches dealing with the analytical applications with the Schiff bases (Ghaedi et al, 2009;Kara et al, 2009;Köse Baran and Bağdat Yaşar, 2012b;Topuz and Macit, 2011).…”

Metal Determinations in Olive Oil

“…The extraction methods used for metal determination in vegetable oils A Schiff base has been suggested for the extraction of metals from oils as an appropriate chelating agent under the optimum extraction conditions (Köse Baran & Bağdat Yaşar, 2010). In recent analytical applications, Schiff bases have been used in order to form complexes due to their good complexing capacity with metals (Afkhami et al, 2009;Ashkenani et al, 2009;Ghaedi et al, 2009;Khedr et al, 2005;Khorrami et al, 2004;Köse Baran & Bağdat Yaşar, 2010;Kurşunlu et al, 2009;Mashhadizadeh et al, 2008;Shamspur et al, 2003;Tantaru et al, 2002;Ziyadanoğulları et al, 2008). The chemists have attended to the Schiff bases and their metal complexes because of their widespread applications in biological systems and industrial uses (Issa et al, 2005;İspir, 2009;Kurtaran et al, 2005;Li et al, 2007;Mohamed, 2006;Neelakantan et al, 2008;Prashanthi et al, 2008;Sharaby, 2007).…”

Effect of non ionic micelles on the chemical speciation of binary complexes of Pb(II), Cd(II) and Hg(II) with L-phenylalanine

“…It affects the immune system, alters genetics and enzyme systems and damages the nervous systems, and the senses of touch, taste and vision (Ashkenani et al, 2009). It has been introduced into the environment as three major forms, elemental Hg, inorganic Hg 2+ and organic Hg.…”
