Synthesis of calix-styrene copolymer carrying thioether groups and examination of the cation-anion extraction properties

This study comprises the synthesis of new calix [4] arene thioether derivative (3),its corresponding oligomer (5) and copolymers (6),which are a selective extractant for toxic metal cations and anions and liquid-liquid and solid-liquid extractions of these compounds. structures of these compounds were described by elemental anaysis,ft-ir,1h nmr and 13c nmr. to determine the ion transport properties of the synthesized compounds,transition metal picrate and dichromate liquid-liquid extraction studies were carried out. it is seen from the extraction results that the calix-styrene copolymer (6) has a good selectivity for the pb2+ and hg2+ cation from the selected metal cations,but it shows poor extraction behavior towards dichromate anion.
