  Synthesis of tetra-substituted calix[4]arene ionophores and their recognition studies toward toxic arsenate anions

  摘要：

  The article displays the synthesis of a family of novel tetra-substituted calix[4]arene ionophores bearing furyl, phenyl, and pyridyl units in the cone conformation. In the synthesis, the lower rims of calix[4]arene scaffold were modified in order to establish the influence of the molecular structure of calixarene on recognition of toxic anions as arsenate by liquid-liquid extraction process. In addition, the effects of solvent, solution conditions (mainly pH), and counter ions (Cl-, NO3-, and SO42-) on the extraction abilities of the ionophores were studied. From the liquid-liquid phase extraction studies, it was observed that the structures of the tetra-substituted calix[4]arenes influenced the extraction percentage of selected toxic anion. Also, thermodynamic parameters, such as the free energy (Delta G degrees) and enthalpy (Delta H degrees) indicated an exothermic nature of extraction and a spontaneous and favorable process.
