“…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).…”
