Bu çalışma için izopropil ksantat sentezlendi ve Pb(II), Fe(III), Cd(II), Mn(II), Cu(II), Ni(II) in zenginleştirilmesinde kullanıldı, FAAS ile analizleri yapıldı. Bilindiği gibi ksantatlar miseller oluştururlar ve metalleri de hemen kompleksleri halinde tutarlar, bundan yararlanılarak izopropil ligand olarak kullanıp cloud point metoduyla eser düzeydeki elementlerin zenginleştirilmesi bu çalışmanın ana amacıdır. Aynı zamanda çalışma da, etki edecek olan; pH, surfaktant miktarı, sıcaklık farkı ve süre gibi parametrelerde incelendi. Standart sapma 2.10 civarlarındayken, tayin aralığı 0.3 ile 1.7 arasında hesaplandı.

Isopropyl xanthate is synthesized and used in various water samples with Pb(II), Fe(III), Cd(II), Mn(II), Cu(II) and Ni(II) ions with flame atomic absorption spectrometry (FAAS) using cloud point extraction (CPE) method. Metal complexes containing isopropyl xanthate are subsequently entrapped in the surfactant micelles. The proposed method is based on cloud point extraction of analyte metal ions without ligand using isopropyl xanthate as surfactant. In this paper, the effects of pH degree, concentration of chelating agent, surfactants, equilibration temperature and time on CPE are examined. Standard deviation was 2.10% between the detection ranges of 0.3-1.7.
