Pirazin Sübstitüe Kaliks[4]arenin Bazı Toksik Metal ve Oksianyon Ekstraksiyon Özelliklerinin İncelenmesi

Abstract

Bu çalışmada, kaliks[4]arenin pirazin karbonil türevi (3) sentezlenmiş ve yapısı spektroskopik yöntemler ile karakterize edilmiştir. Ayrıca, bu bileşik büyük çevresel problemlere sebep olan toksik özelliğe sahip metaller (Na⁺, Cs⁺, Co²⁺, Ni²⁺, Cu²⁺, Cd²⁺, Pb²⁺ ve Hg²⁺) ve oksianyonların’ın (kromat ve arsenat) sıvı-sıvı ekstraksiyon çalışmaların da kullanılmıştır. Ekstraksiyon sonuçlarına göre düşük pH larda kromat (pH=1,5) ve arsenat (pH=3,5) anyonlarının yüksek oranda sulu fazdan organik faza taşındığı görülmüştür. Kaliksaren türevi (3) ile oksianyonlar arasında ki kompleks oranı job’s plot analiz yöntemi ile 1:1 olduğu tespit edilmiştir. Ayrıca Bileşik 3, çalışılan toksik metalleri ise yüksek oranda sulu fazdan organik faza taşımıştır.
