Determination of crown ether complexation with metal ıons by application Job’s Plot method to conductometry
Öz
In this study, ion-dipole interactions between benzo-thio and benzo-oxo crown ethers and metal ions were determined by adaptation of Job’s Plot method to conductivity (Solvent system: 50% Acetonitrile / water). The complexation properties of the crown ethers previously synthesized using microwave synthesis method (U1 (bis (1,2-dibenzo) octathio tetracarbonyl-29-crown-6), U2 (bis (1,2-dibenzo) tetrathio tetracarbonyl-29-crown-6)) and salts (NaCl, KCl, MgCl2, CaCl2, ZnCl2, FeSO4, AgNO3, CoCl2) were investigated. The complexation rate, complexation constant (Ke) and Free Gibbs Enthalpy (ΔGθ) of the crown ether-cation complex were calculated. According to the studies carried out by conductometry, the complexation constant for the compound U1 decreased in the direction Na+> Zn2+> Ca2+> Ag+> K+> Mg2+> Co2+> Fe2+, while for the U2 compound Zn2+> Fe2+> Na+> K+> Co2+> Ag+> Ca2+> Mg2+ were observed. According to the results of this study, selected crown ethers can be used for metal sensor, inhibitor or activator for enzymes in bioorganisms and metal trap in industrial-environmental applications.

Taç eterlerin metal iyonları ile kompleksleşmesinin kondüktometriye Job’s Plot yönteminin uygulanması ile belirlenmesi
Öz
Bu çalışma kapsamında benzo-tiyo ve benzo-okso taç eterler ile metal iyonları arasındaki iyon-dipol etkileşmeleri Job’s Plot yönteminin kondüktometriye uyarlanmasıyla belirlendi (Çözücü sistemi: %50 Asetonitril/su). Daha önce verilen mikrodalga sentez yöntemi kullanılarak yeniden sentezlenen U1 (bis(1,2-dibenzo) oktatiyo tetrakarbonil-29-crown-6), U2 (bis(1,2-dibenzo) tetratiyo tetrakarbonil-29-crown-6) taç eterlerinin NaCl, KCl, MgCl2, CaCl2, ZnCl2, FeSO4, AgNO3, CoCl2 metal tuzlarıyla komplesleşmeleri incelendi. Taç eter-katyon kompleksinin kompleksleşme oranı, kompleksleşme sabiti (Ke) ve Serbest Gibbs Enerjisi (ΔGθ ) hesaplandı. Kondüktometri ile gerçekleştirilen çalışmalara göre U1 bileşiği için kompleksleşme sabiti Na+ > Zn2+ > Ca2+ > Ag+ > K+ > Mg2+ > Co2+ > Fe2+ yönünde azalırken, U2 bileşiği için Zn2+ > Fe2+ > Na+ > K+ > Co2+ > Ag+ > Ca2+ > Mg2+ yönünde değiştiği gözlemlenmiştir. Bu çalışma sonuçlarına göre taç eterler metal sensörü, biyoorganizmalardaki enzimler için inhibitör veya aktivatör ve sanayi-çevre uygulamalarında metal iyonlarının giderimi için kullanılabilirler.
